Summary
hw/net/xgmac.c in the XGMAC Ethernet controller in QEMU before 07-20-2020 has a buffer overflow. This occurs during packet transmission and affects the highbank and midway emulated machines. A guest user or process could use this flaw to crash the QEMU process on the host, resulting in a denial of service or potential privileged code execution. This was fixed in commit 5519724a13664b43e225ca05351c60b4468e4555.

Summary
An out-of-bounds heap buffer access flaw was found in the way the iSCSI Block driver in QEMU versions 2.12.0 before 4.2.1 handled a response coming from an iSCSI server while checking the status of a Logical Address Block (LBA) in an iscsi_co_block_status() routine. A remote user could use this flaw to crash the QEMU process, resulting in a denial of service or potential execution of arbitrary code with privileges of the QEMU process on the host.

Summary
An off-by-one read/write issue was found in the SDHCI device of QEMU. It occurs when reading/writing the Buffer Data Port Register in sdhci_read_dataport and sdhci_write_dataport, respectively, if data_count == block_size. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition.

In QEMU through 5.0.0, an integer overflow was found in the SM501 display driver implementation. This flaw occurs in the COPY_AREA macro while handling MMIO write operations through the sm501_2d_engine_write() callback. A local attacker could abuse this flaw to crash the QEMU process in sm501_2d_operation() in hw/display/sm501.c on the host, resulting in a denial of service.

Summary
The hardware emulation in the of_dpa_cmd_add_l2_flood of rocker device model in QEMU, as used in 7.0.0 and earlier, allows remote attackers to crash the host qemu and potentially execute code on the host via execute a malformed program in the guest OS. Note: This has been disputed by multiple third parties as not a valid vulnerability due to the rocker device not falling within the virtualization use case.

Summary
A heap buffer overflow was found in the floppy disk emulator of QEMU up to 6.0.0 (including). It could occur in fdctrl_transfer_handler() in hw/block/fdc.c while processing DMA read data transfers from the floppy drive to the guest system. A privileged guest user could use this flaw to crash the QEMU process on the host resulting in DoS scenario, or potential information leakage from the host memory.

Summary
The (1) fw_cfg_write and (2) fw_cfg_read functions in hw/nvram/fw_cfg.c in QEMU before 2.4, when built with the Firmware Configuration device emulation support, allow guest OS users with the CAP_SYS_RAWIO privilege to cause a denial of service (out-of-bounds read or write access and process crash) or possibly execute arbitrary code via an invalid current entry value in a firmware configuration.

Summary
In QEMU 4.1.0, an out-of-bounds read flaw was found in the ATI VGA implementation. It occurs in the ati_cursor_define() routine while handling MMIO write operations through the ati_mm_write() callback. A malicious guest could abuse this flaw to crash the QEMU process, resulting in a denial of service.

Summary
The vmsvga_fifo_run function in hw/display/vmware_vga.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (out-of-bounds write and QEMU process crash) via vectors related to cursor.mask[] and cursor.image[] array sizes when processing a DEFINE_CURSOR svga command.

Summary
The pit_ioport_read in i8254.c in the Linux kernel before 2.6.33 and QEMU before 2.3.1 does not distinguish between read lengths and write lengths, which might allow guest OS users to execute arbitrary code on the host OS by triggering use of an invalid index.

Summary
The vmsvga_fifo_read_raw function in hw/display/vmware_vga.c in QEMU allows local guest OS administrators to obtain sensitive host memory information or cause a denial of service (QEMU process crash) by changing FIFO registers and issuing a VGA command, which triggers an out-of-bounds read.

Summary
An out-of-bounds read/write access flaw was found in the USB emulator of the QEMU in versions before 5.2.0. This issue occurs while processing USB packets from a guest when USBDevice 'setup_len' exceeds its 'data_buf[4096]' in the do_token_in, do_token_out routines. This flaw allows a guest user to crash the QEMU process, resulting in a denial of service, or the potential execution of arbitrary code with the privileges of the QEMU process on the host.

Summary
The qemu-nbd server in QEMU (aka Quick Emulator), when built with the Network Block Device (NBD) Server support, allows remote attackers to cause a denial of service (segmentation fault and server crash) by leveraging failure to ensure that all initialization occurs before talking to a client in the nbd_negotiate function.

Summary
Memory leak in the usb_xhci_exit function in hw/usb/hcd-xhci.c in QEMU (aka Quick Emulator), when the xhci uses msix, allows local guest OS administrators to cause a denial of service (memory consumption and possibly QEMU process crash) by repeatedly unplugging a USB device.

Summary
Quick Emulator (Qemu) built with the VirtFS, host directory sharing via Plan 9 File System (9pfs) support, is vulnerable to an improper access control issue. It could occur while accessing files on a shared host directory. A privileged user inside guest could use this flaw to access host file system beyond the shared folder and potentially escalating their privileges on a host.

Summary
QEMU (aka Quick Emulator) built with the NE2000 device emulation support is vulnerable to an OOB r/w access issue. It could occur while performing 'ioport' r/w operations. A privileged (CAP_SYS_RAWIO) user/process could use this flaw to leak or corrupt QEMU memory bytes.

Summary
A deadlock issue was found in the AHCI controller device of QEMU. It occurs on a software reset (ahci_reset_port) while handling a host-to-device Register FIS (Frame Information Structure) packet from the guest. A privileged user inside the guest could use this flaw to hang the QEMU process on the host, resulting in a denial of service condition. The highest threat from this vulnerability is to system availability.

Summary
A stack buffer overflow flaw was found in the Quick Emulator (QEMU) before 2.9 built with the Network Block Device (NBD) client support. The flaw could occur while processing server's response to a 'NBD_OPT_LIST' request. A malicious NBD server could use this issue to crash a remote NBD client resulting in DoS or potentially execute arbitrary code on client host with privileges of the QEMU process.

Summary
The imx_fec_do_tx function in hw/net/imx_fec.c in QEMU (aka Quick Emulator) does not properly limit the buffer descriptor count when transmitting packets, which allows local guest OS administrators to cause a denial of service (infinite loop and QEMU process crash) via vectors involving a buffer descriptor with a length of 0 and crafted values in bd.flags.

Summary
VNC server implementation in Quick Emulator (QEMU) 2.11.0 and older was found to be vulnerable to an unbounded memory allocation issue, as it did not throttle the framebuffer updates sent to its client. If the client did not consume these updates, VNC server allocates growing memory to hold onto this data. A malicious remote VNC client could use this flaw to cause DoS to the server host.

Summary
The QMP guest_exec command in QEMU 4.0.0 and earlier is prone to OS command injection, which allows the attacker to achieve code execution, denial of service, or information disclosure by sending a crafted QMP command to the listening server. Note: This has been disputed as a non-issue since QEMU's -qmp interface is meant to be used by trusted users. If one is able to access this interface via a tcp socket open to the internet, then it is an insecure configuration issue

Summary
Multiple use-after-free vulnerabilities in vnc.c in the VNC server in QEMU 0.10.6 and earlier might allow guest OS users to execute arbitrary code on the host OS by establishing a connection from a VNC client and then (1) disconnecting during data transfer, (2) sending a message using incorrect integer data types, or (3) using the Fuzzy Screen Mode protocol, related to double free vulnerabilities.

Summary
Multiple integer overflows in the USB Net device emulator (hw/usb/dev-network.c) in QEMU before 2.5.1 allow local guest OS administrators to cause a denial of service (QEMU process crash) or obtain sensitive host memory information via a remote NDIS control message packet that is mishandled in the (1) rndis_query_response, (2) rndis_set_response, or (3) usb_net_handle_dataout function.

Summary
An integer overflow issue was found in the vmxnet3 NIC emulator of the QEMU for versions up to v5.2.0. It may occur if a guest was to supply invalid values for rx/tx queue size or other NIC parameters. A privileged guest user may use this flaw to crash the QEMU process on the host resulting in DoS scenario.

Summary
The net_tx_pkt_do_sw_fragmentation function in hw/net/net_tx_pkt.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (infinite loop and QEMU process crash) via a zero length for the current fragment length.

Summary
hw/ide/core.c in QEMU does not properly restrict the commands accepted by an ATAPI device, which allows guest users to cause a denial of service or possibly have unspecified other impact via certain IDE commands, as demonstrated by a WIN_READ_NATIVE_MAX command to an empty drive, which triggers a divide-by-zero error and instance crash.

Summary
Integer signedness error in the NE2000 emulator in QEMU 0.8.2, as used in Xen and possibly other products, allows local users to trigger a heap-based buffer overflow via certain register values that bypass sanity checks, aka QEMU NE2000 "receive" integer signedness error. NOTE: this identifier was inadvertently used by some sources to cover multiple issues that were labeled "NE2000 network driver and the socket code," but separate identifiers have been created for the individual vulnerabilities since there are sometimes different fixes; see CVE-2007-5729 and CVE-2007-5730.

Summary
The sosendto function in slirp/udp.c in QEMU before 2.1.2 allows local users to cause a denial of service (NULL pointer dereference) by sending a udp packet with a value of 0 in the source port and address, which triggers access of an uninitialized socket.

Summary
The NE2000 emulator in QEMU 0.8.2 allows local users to execute arbitrary code by writing Ethernet frames with a size larger than the MTU to the EN0_TCNT register, which triggers a heap-based buffer overflow in the slirp library, aka NE2000 "mtu" heap overflow. NOTE: some sources have used CVE-2007-1321 to refer to this issue as part of "NE2000 network driver and the socket code," but this is the correct identifier for the mtu overflow vulnerability.

Summary
qmp_guest_file_read in qga/commands-posix.c and qga/commands-win32.c in qemu-ga (aka QEMU Guest Agent) in QEMU 2.12.50 has an integer overflow causing a g_malloc0() call to trigger a segmentation fault when trying to allocate a large memory chunk. The vulnerability can be exploited by sending a crafted QMP command (including guest-file-read with a large count value) to the agent via the listening socket.

Summary
Multiple heap-based buffer overflows in the cirrus_invalidate_region function in the Cirrus VGA extension in QEMU 0.8.2, as used in Xen and possibly other products, might allow local users to execute arbitrary code via unspecified vectors related to "attempting to mark non-existent regions as dirty," aka the "bitblt" heap overflow.

Summary
A flaw was found in the way qemu v1.3.0 and later (virtio-rng) validates addresses when guest accesses the config space of a virtio device. If the virtio device has zero/small sized config space, such as virtio-rng, a privileged guest user could use this flaw to access the matching host's qemu address space and thus increase their privileges on the host.

Summary
It was discovered that the update for the virt:rhel module in the RHSA-2020:4676 (https://access.redhat.com/errata/RHSA-2020:4676) erratum released as part of Red Hat Enterprise Linux 8.3 failed to include the fix for the qemu-kvm component issue CVE-2020-10756, which was previously corrected in virt:rhel/qemu-kvm via erratum RHSA-2020:4059 (https://access.redhat.com/errata/RHSA-2020:4059). CVE-2021-20295 was assigned to that Red Hat specific security regression. For more details about the original security issue CVE-2020-10756, refer to bug 1835986 or the CVE page: https://access.redhat.com/security/cve/CVE-2020-10756.

Summary
Buffer overflow in the e1000_receive function in the e1000 device driver (hw/e1000.c) in QEMU 1.3.0-rc2 and other versions, when the SBP and LPE flags are disabled, allows remote attackers to cause a denial of service (guest OS crash) and possibly execute arbitrary guest code via a large packet.

Summary
A reachable assertion issue was found in the USB EHCI emulation code of QEMU. It could occur while processing USB requests due to missing handling of DMA memory map failure. A malicious privileged user within the guest may abuse this flaw to send bogus USB requests and crash the QEMU process on the host, resulting in a denial of service.

Summary
A flaw was found in the USB redirector device (usb-redir) of QEMU. Small USB packets are combined into a single, large transfer request, to reduce the overhead and improve performance. The combined size of the bulk transfer is used to dynamically allocate a variable length array (VLA) on the stack without proper validation. Since the total size is not bounded, a malicious guest could use this flaw to influence the array length and cause the QEMU process to perform an excessive allocation on the stack, resulting in a denial of service.

Summary
Several memory leaks were found in the virtio vhost-user GPU device (vhost-user-gpu) of QEMU in versions up to and including 6.0. They exist in contrib/vhost-user-gpu/vhost-user-gpu.c and contrib/vhost-user-gpu/virgl.c due to improper release of memory (i.e., free) after effective lifetime.

Summary
An assertion failure issue was found in the Network Block Device(NBD) Server in all QEMU versions before QEMU 5.0.1. This flaw occurs when an nbd-client sends a spec-compliant request that is near the boundary of maximum permitted request length. A remote nbd-client could use this flaw to crash the qemu-nbd server resulting in a denial of service.

Summary
Multiple integer overflows in the (1) v9fs_xattr_read and (2) v9fs_xattr_write functions in hw/9pfs/9p.c in QEMU (aka Quick Emulator) allow local guest OS administrators to cause a denial of service (QEMU process crash) via a crafted offset, which triggers an out-of-bounds access.

Summary
An out-of-bounds heap buffer access issue was found in the ARM Generic Interrupt Controller emulator of QEMU up to and including qemu 4.2.0on aarch64 platform. The issue occurs because while writing an interrupt ID to the controller memory area, it is not masked to be 4 bits wide. It may lead to the said issue while updating controller state fields and their subsequent processing. A privileged guest user may use this flaw to crash the QEMU process on the host resulting in DoS scenario.

Summary
QEMU (aka Quick Emulator) built with the Virtio GPU Device emulator support is vulnerable to a memory leakage issue. It could occur while updating the cursor data in update_cursor_data_virgl. A guest user/process could use this flaw to leak host memory bytes, resulting in DoS for a host.

Summary
The QMP migrate command in QEMU version 4.0.0 and earlier is vulnerable to OS command injection, which allows the remote attacker to achieve code execution, denial of service, or information disclosure by sending a crafted QMP command to the listening server. Note: This has been disputed as a non-issue since QEMU's -qmp interface is meant to be used by trusted users. If one is able to access this interface via a tcp socket open to the internet, then it is an insecure configuration issue

Summary
QEMU (aka Quick Emulator) built with the ColdFire Fast Ethernet Controller emulator support is vulnerable to an infinite loop issue. It could occur while receiving packets in 'mcf_fec_receive'. A privileged user/process inside guest could use this issue to crash the QEMU process on the host leading to DoS.

Summary
In QEMU 1:4.1-1, 1:2.1+dfsg-12+deb8u6, 1:2.8+dfsg-6+deb9u8, 1:3.1+dfsg-8~deb10u1, 1:3.1+dfsg-8+deb10u2, and 1:2.1+dfsg-12+deb8u12 (fixed), when executing script in lsi_execute_script(), the LSI scsi adapter emulator advances 's->dsp' index to read next opcode. This can lead to an infinite loop if the next opcode is empty. Move the existing loop exit after 10k iterations so that it covers no-op opcodes as well.

Summary
In QEMU 5.0.0 and earlier, es1370_transfer_audio in hw/audio/es1370.c does not properly validate the frame count, which allows guest OS users to trigger an out-of-bounds access during an es1370_write() operation.

Summary
A flaw was found in the QXL display device emulation in QEMU. A double fetch of guest controlled values `cursor->header.width` and `cursor->header.height` can lead to the allocation of a small cursor object followed by a subsequent heap-based buffer overflow. A malicious privileged guest user could use this flaw to crash the QEMU process on the host or potentially execute arbitrary code within the context of the QEMU process.

Summary
The Floppy Disk Controller (FDC) in QEMU, as used in Xen 4.5.x and earlier and KVM, allows local guest users to cause a denial of service (out-of-bounds write and guest crash) or possibly execute arbitrary code via the (1) FD_CMD_READ_ID, (2) FD_CMD_DRIVE_SPECIFICATION_COMMAND, or other unspecified commands, aka VENOM.

Summary
Memory leak in the virgl_cmd_resource_unref function in hw/display/virtio-gpu-3d.c in QEMU (aka Quick Emulator) allows local guest OS users to cause a denial of service (host memory consumption) via a large number of VIRTIO_GPU_CMD_RESOURCE_UNREF commands sent without detaching the backing storage beforehand.

Summary
An off-by-one error was found in the SCSI device emulation in QEMU. It could occur while processing MODE SELECT commands in mode_sense_page() if the 'page' argument was set to MODE_PAGE_ALLS (0x3f). A malicious guest could use this flaw to potentially crash QEMU, resulting in a denial of service condition.

Summary
Buffer overflow in hw/scsi-disk.c in the SCSI subsystem in QEMU before 0.15.2, as used by Xen, might allow local guest users with permission to access the CD-ROM to cause a denial of service (guest crash) via a crafted SAI READ CAPACITY SCSI command. NOTE: this is only a vulnerability when root has manually modified certain permissions or ACLs.

Summary
Integer overflow in the net_tx_pkt_init function in hw/net/net_tx_pkt.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (QEMU process crash) via the maximum fragmentation count, which triggers an unchecked multiplication and NULL pointer dereference.

Summary
A flaw was found in the USB redirector device emulation of QEMU in versions prior to 6.1.0-rc2. It occurs when dropping packets during a bulk transfer from a SPICE client due to the packet queue being full. A malicious SPICE client could use this flaw to make QEMU call free() with faked heap chunk metadata, resulting in a crash of QEMU or potential code execution with the privileges of the QEMU process on the host.

Summary
The patch for CVE-2020-17380/CVE-2020-25085 was found to be ineffective, thus making QEMU vulnerable to the out-of-bounds read/write access issues previously found in the SDHCI controller emulation code. This flaw allows a malicious privileged guest to crash the QEMU process on the host, resulting in a denial of service or potential code execution. QEMU up to (including) 5.2.0 is affected by this.

Summary
A flaw was found in qemu Media Transfer Protocol (MTP). The code opening files in usb_mtp_get_object and usb_mtp_get_partial_object and directories in usb_mtp_object_readdir doesn't consider that the underlying filesystem may have changed since the time lstat(2) was called in usb_mtp_object_alloc, a classical TOCTTOU problem. An attacker with write access to the host filesystem shared with a guest can use this property to navigate the host filesystem in the context of the QEMU process and read any file the QEMU process has access to. Access to the filesystem may be local or via a network share protocol such as CIFS.

Summary
An out-of-bounds write vulnerability was found in the virtio vhost-user GPU device (vhost-user-gpu) of QEMU in versions up to and including 6.0. The flaw occurs while processing the 'VIRTIO_GPU_CMD_GET_CAPSET' command from the guest. It could allow a privileged guest user to crash the QEMU process on the host, resulting in a denial of service condition, or potential code execution with the privileges of the QEMU process.

Summary
QEMU, through version 2.10 and through version 3.1.0, is vulnerable to an out-of-bounds read of up to 128 bytes in the hw/i2c/i2c-ddc.c:i2c_ddc() function. A local attacker with permission to execute i2c commands could exploit this to read stack memory of the qemu process on the host.

Summary
The pvscsi_ring_pop_req_descr function in hw/scsi/vmw_pvscsi.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (infinite loop and QEMU process crash) by leveraging failure to limit process IO loop to the ring size.

Summary
A potential DoS flaw was found in the virtio-fs shared file system daemon (virtiofsd) implementation of the QEMU version >= v5.0. Virtio-fs is meant to share a host file system directory with a guest via virtio-fs device. If the guest opens the maximum number of file descriptors under the shared directory, a denial of service may occur. This flaw allows a guest user/process to cause this denial of service on the host.

Summary
A flaw was found in qemu Media Transfer Protocol (MTP) before version 3.1.0. A path traversal in the in usb_mtp_write_data function in hw/usb/dev-mtp.c due to an improper filename sanitization. When the guest device is mounted in read-write mode, this allows to read/write arbitrary files which may lead do DoS scenario OR possibly lead to code execution on the host.

Summary
QEMU through 8.0.0 could trigger a division by zero in scsi_disk_reset in hw/scsi/scsi-disk.c because scsi_disk_emulate_mode_select does not prevent s->qdev.blocksize from being 256. This stops QEMU and the guest immediately.

Summary
A heap buffer overflow flaw was found in QEMU's Cirrus CLGD 54xx VGA emulator's VNC display driver support before 2.9; the issue could occur when a VNC client attempted to update its display after a VGA operation is performed by a guest. A privileged user/process inside a guest could use this flaw to crash the QEMU process or, potentially, execute arbitrary code on the host with privileges of the QEMU process.

Summary
The Network Block Device (NBD) server in Quick Emulator (QEMU) before 2.11 is vulnerable to a denial of service issue. It could occur if a client sent large option requests, making the server waste CPU time on reading up to 4GB per request. A client could use this flaw to keep the NBD server from serving other requests, resulting in DoS.

Summary
The pciej_write function in hw/acpi_piix4.c in the PIIX4 Power Management emulation in qemu-kvm does not check if a device is hotpluggable before unplugging the PCI-ISA bridge, which allows privileged guest users to cause a denial of service (guest crash) and possibly execute arbitrary code by sending a crafted value to the 0xae08 (PCI_EJ_BASE) I/O port, which leads to a use-after-free related to "active qemu timers."

An user able to alter the savevm data (either on the disk or over the wire during migration) could use this flaw to to corrupt QEMU process memory on the (destination) host, which could potentially result in arbitrary code execution on the host with the privileges of the QEMU process.

Summary
The esp_reg_write function in hw/scsi/esp.c in the 53C9X Fast SCSI Controller (FSC) support in QEMU does not properly check command buffer length, which allows local guest OS administrators to cause a denial of service (out-of-bounds write and QEMU process crash) or potentially execute arbitrary code on the QEMU host via unspecified vectors.

Summary
The mcf_fec_do_tx function in hw/net/mcf_fec.c in QEMU (aka Quick Emulator) does not properly limit the buffer descriptor count when transmitting packets, which allows local guest OS administrators to cause a denial of service (infinite loop and QEMU process crash) via vectors involving a buffer descriptor with a length of 0 and crafted values in bd.flags.

Summary
QEMU (aka Quick Emulator) built with the USB EHCI emulation support is vulnerable to a null pointer dereference flaw. It could occur when an application attempts to write to EHCI capabilities registers. A privileged user inside quest could use this flaw to crash the QEMU process instance resulting in DoS.

Summary
A stack-based buffer overflow vulnerability was found in NBD server implementation in qemu before 2.11 allowing a client to request an export name of size up to 4096 bytes, which in fact should be limited to 256 bytes, causing an out-of-bounds stack write in the qemu process. If NBD server requires TLS, the attacker cannot trigger the buffer overflow without first successfully negotiating TLS.

Summary
The load_multiboot function in hw/i386/multiboot.c in Quick Emulator (aka QEMU) allows local guest OS users to execute arbitrary code on the QEMU host via a mh_load_end_addr value greater than mh_bss_end_addr, which triggers an out-of-bounds read or write memory access.

Summary
A flaw was found in the QEMU implementation of VMWare's paravirtual RDMA device in versions prior to 6.1.0. The issue occurs while handling a "PVRDMA_REG_DSRHIGH" write from the guest and may result in a crash of QEMU or cause undefined behavior due to the access of an uninitialized pointer. The highest threat from this vulnerability is to system availability.

Summary
An out-of-bounds read flaw was found in the QXL display device emulation in QEMU. The qxl_phys2virt() function does not check the size of the structure pointed to by the guest physical address, potentially reading past the end of the bar space into adjacent pages. A malicious guest user could use this flaw to crash the QEMU process on the host causing a denial of service condition.

Summary
Integer overflow in hw/virtio/virtio-crypto.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (QEMU process crash) or possibly execute arbitrary code on the host via a crafted virtio-crypto request, which triggers a heap-based buffer overflow.

Summary
Qemu before 2.0 block driver for Hyper-V VHDX Images is vulnerable to infinite loops and other potential issues when calculating BAT entries, due to missing bounds checks for block_size and logical_sector_size variables. These are used to derive other fields like 'sectors_per_block' etc. A user able to alter the Qemu disk image could ise this flaw to crash the Qemu instance resulting in DoS.

Summary
vmstate_xhci_event in hw/usb/hcd-xhci.c in QEMU 1.6.0 does not terminate the list with the VMSTATE_END_OF_LIST macro, which allows attackers to cause a denial of service (out-of-bounds access, infinite loop, and memory corruption) and possibly gain privileges via unspecified vectors.

Summary
The slirp_smb function in net/slirp.c in QEMU 2.3.0 and earlier creates temporary files with predictable names, which allows local users to cause a denial of service (instantiation failure) by creating /tmp/qemu-smb.*-* files before the program.

Summary
A flaw was found in the virtio-fs shared file system daemon (virtiofsd) of QEMU. The new 'xattrmap' option may cause the 'security.capability' xattr in the guest to not drop on file write, potentially leading to a modified, privileged executable in the guest. In rare circumstances, this flaw could be used by a malicious user to elevate their privileges within the guest.

This could allow a malicious user to overwrite local variables allocated on the stack. Specifically, the `out_sg` variable could be used to read a part of process memory and send it to the wire, causing an information leak."

Summary
A flaw was found in the QEMU virtio-fs shared file system daemon (virtiofsd) implementation. This flaw is strictly related to CVE-2018-13405. A local guest user can create files in the directories shared by virtio-fs with unintended group ownership in a scenario where a directory is SGID to a certain group and is writable by a user who is not a member of the group. This could allow a malicious unprivileged user inside the guest to gain access to resources accessible to the root group, potentially escalating their privileges within the guest. A malicious local user in the host might also leverage this unexpected executable file created by the guest to escalate their privileges on the host system.

A local guest user can create files in the directories shared by virtio-fs with unintended group ownership in a scenario where a directory is SGID to a certain group and is writable by a user who is not a member of the group. This could allow a malicious unprivileged user inside the guest to gain access to resources accessible to the root group, potentially escalating their privileges within the guest. A malicious local user in the host might also leverage this unexpected executable file created by the guest to escalate their privileges on the host system."

Summary
A NULL pointer dereference issue was found in the block mirror layer of QEMU in versions prior to 6.2.0. The `self` pointer is dereferenced in mirror_wait_on_conflicts() without ensuring that it's not NULL. A malicious unprivileged user within the guest could use this flaw to crash the QEMU process on the host when writing data reaches the threshold of mirroring node.

Summary
A DMA reentrancy issue was found in the Tulip device emulation in QEMU. When Tulip reads or writes to the rx/tx descriptor or copies the rx/tx frame, it doesn't check whether the destination address is its own MMIO address. This can cause the device to trigger MMIO handlers multiple times, possibly leading to a stack or heap overflow. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition.

Summary
A DMA reentrancy issue was found in the NVM Express Controller (NVME) emulation in QEMU. This CVE is similar to CVE-2021-3750 and, just like it, when the reentrancy write triggers the reset function nvme_ctrl_reset(), data structs will be freed leading to a use-after-free issue. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition or, potentially, executing arbitrary code within the context of the QEMU process on the host.

Summary
The virtio_net_bad_features function in hw/virtio-net.c in the virtio-net driver in the Linux kernel before 2.6.26, when used on a guest OS in conjunction with qemu-kvm 0.11.0 or KVM 83, allows remote attackers to cause a denial of service (guest OS crash, and an associated qemu-kvm process exit) by sending a large amount of network traffic to a TCP port on the guest OS, related to a virtio-net whitelist that includes an improper implementation of TCP Segment Offloading (TSO).

Summary
A NULL pointer dereference flaw was found in the floppy disk emulator of QEMU. This issue occurs while processing read/write ioport commands if the selected floppy drive is not initialized with a block device. This flaw allows a privileged guest user to crash the QEMU process on the host, resulting in a denial of service. The highest threat from this vulnerability is to system availability.

Summary
An infinite loop flaw was found in the e1000 NIC emulator of the QEMU. This issue occurs while processing transmits (tx) descriptors in process_tx_desc if various descriptor fields are initialized with invalid values. This flaw allows a guest to consume CPU cycles on the host, resulting in a denial of service. The highest threat from this vulnerability is to system availability.

Summary

Summary
The disas_insn function in target/i386/translate.c in QEMU before 2.9.0, when TCG mode without hardware acceleration is used, does not limit the instruction size, which allows local users to gain privileges by creating a modified basic block that injects code into a setuid program, as demonstrated by procmail. NOTE: the vendor has stated "this bug does not violate any security guarantees QEMU makes.

Summary
The esp_do_dma function in hw/scsi/esp.c in QEMU (aka Quick Emulator), when built with ESP/NCR53C9x controller emulation support, allows local guest OS administrators to cause a denial of service (out-of-bounds write and QEMU process crash) or execute arbitrary code on the QEMU host via vectors involving DMA read into ESP command buffer.

Summary
A use-after-free vulnerability was found in the virtio-net device of QEMU. It could occur when the descriptor's address belongs to the non direct access region, due to num_buffers being set after the virtqueue elem has been unmapped. A malicious guest could use this flaw to crash QEMU, resulting in a denial of service condition, or potentially execute code on the host with the privileges of the QEMU process.

Summary
The is_rndis function in the USB Net device emulator (hw/usb/dev-network.c) in QEMU before 2.5.1 does not properly validate USB configuration descriptor objects, which allows local guest OS administrators to cause a denial of service (NULL pointer dereference and QEMU process crash) via vectors involving a remote NDIS control message packet.

Summary
An integer overflow was found in the QEMU implementation of VMWare's paravirtual RDMA device in versions prior to 6.1.0. The issue occurs while handling a "PVRDMA_REG_DSRHIGH" write from the guest due to improper input validation. This flaw allows a privileged guest user to make QEMU allocate a large amount of memory, resulting in a denial of service. The highest threat from this vulnerability is to system availability.

Summary
Multiple integer overflows in the block drivers in QEMU, possibly before 2.0.0, allow local users to cause a denial of service (crash) via a crafted catalog size in (1) the parallels_open function in block/parallels.c or (2) bochs_open function in bochs.c, a large L1 table in the (3) qcow2_snapshot_load_tmp in qcow2-snapshot.c or (4) qcow2_grow_l1_table function in qcow2-cluster.c, (5) a large request in the bdrv_check_byte_request function in block.c and other block drivers, (6) crafted cluster indexes in the get_refcount function in qcow2-refcount.c, or (7) a large number of blocks in the cloop_open function in cloop.c, which trigger buffer overflows, memory corruption, large memory allocations and out-of-bounds read and writes.

Summary
Quick Emulator (Qemu) built with the VirtFS, host directory sharing via Plan 9 File System(9pfs) support, is vulnerable to an improper access control issue. It could occur while accessing virtfs metadata files in mapped-file security mode. A guest user could use this flaw to escalate their privileges inside guest.

Summary
A stack overflow via an infinite recursion vulnerability was found in the eepro100 i8255x device emulator of QEMU. This issue occurs while processing controller commands due to a DMA reentry issue. This flaw allows a guest user or process to consume CPU cycles or crash the QEMU process on the host, resulting in a denial of service. The highest threat from this vulnerability is to system availability.

Summary
An integer overflow and buffer overflow issues were found in the ACPI Error Record Serialization Table (ERST) device of QEMU in the read_erst_record() and write_erst_record() functions. Both issues may allow the guest to overrun the host buffer allocated for the ERST memory device. A malicious guest could use these flaws to crash the QEMU process on the host.

Summary
A flaw was found in QEMU in the implementation of the Pointer Authentication (PAuth) support for ARM introduced in version 4.0 and fixed in version 5.0.0. A general failure of the signature generation process caused every PAuth-enforced pointer to be signed with the same signature. A local attacker could obtain the signature of a protected pointer and abuse this flaw to bypass PAuth protection for all programs running on QEMU.

Summary
Quick emulator (Qemu) built with the Cirrus CLGD 54xx VGA Emulator support is vulnerable to a divide by zero issue. It could occur while copying VGA data when cirrus graphics mode was set to be VGA. A privileged user inside guest could use this flaw to crash the Qemu process instance on the host, resulting in DoS.

Summary
An assertion-failure flaw was found in Qemu before 2.10.1, in the Network Block Device (NBD) server's initial connection negotiation, where the I/O coroutine was undefined. This could crash the qemu-nbd server if a client sent unexpected data during connection negotiation. A remote user or process could use this flaw to crash the qemu-nbd server resulting in denial of service.

Summary
QEMU (aka Quick Emulator) built to use 'address_space_translate' to map an address to a MemoryRegionSection is vulnerable to an OOB r/w access issue. It could occur while doing pci_dma_read/write calls. Affects QEMU versions >= 1.6.0 and <= 2.3.1. A privileged user inside guest could use this flaw to crash the guest instance resulting in DoS.

Summary
The (1) BMDMA and (2) AHCI HBA interfaces in the IDE functionality in QEMU 1.0 through 2.1.3 have multiple interpretations of a function's return value, which allows guest OS users to cause a host OS denial of service (memory consumption or infinite loop, and system crash) via a PRDT with zero complete sectors, related to the bmdma_prepare_buf and ahci_dma_prepare_buf functions.

Summary
A use-after-free vulnerability was found in the LSI53C895A SCSI Host Bus Adapter emulation of QEMU. The flaw occurs while processing repeated messages to cancel the current SCSI request via the lsi_do_msgout function. This flaw allows a malicious privileged user within the guest to crash the QEMU process on the host, resulting in a denial of service.

Summary
A DMA reentrancy issue was found in the USB EHCI controller emulation of QEMU. EHCI does not verify if the Buffer Pointer overlaps with its MMIO region when it transfers the USB packets. Crafted content may be written to the controller's registers and trigger undesirable actions (such as reset) while the device is still transferring packets. This can ultimately lead to a use-after-free issue. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition, or potentially execute arbitrary code within the context of the QEMU process on the host. This flaw affects QEMU versions before 7.0.0.

Summary
Heap-based buffer overflow in QEMU 0.8.2, as used in Xen and possibly other products, allows local users to execute arbitrary code via crafted data in the "net socket listen" option, aka QEMU "net socket" heap overflow. NOTE: some sources have used CVE-2007-1321 to refer to this issue as part of "NE2000 network driver and the socket code," but this is the correct identifier for the individual net socket listen vulnerability.

Summary
An issue was discovered in ide_dma_cb() in hw/ide/core.c in QEMU 2.4.0 through 4.2.0. The guest system can crash the QEMU process in the host system via a special SCSI_IOCTL_SEND_COMMAND. It hits an assertion that implies that the size of successful DMA transfers there must be a multiple of 512 (the size of a sector). NOTE: a member of the QEMU security team disputes the significance of this issue because a "privileged guest user has many ways to cause similar DoS effect, without triggering this assert.

Summary
The xhci_ring_fetch function in hw/usb/hcd-xhci.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (infinite loop and QEMU process crash) by leveraging failure to limit the number of link Transfer Request Blocks (TRB) to process.

Summary
A heap-based buffer overflow was found in QEMU through 5.0.0 in the SDHCI device emulation support. It could occur while doing a multi block SDMA transfer via the sdhci_sdma_transfer_multi_blocks() routine in hw/sd/sdhci.c. A guest user or process could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition, or potentially execute arbitrary code with privileges of the QEMU process on the host.

Summary
QEMU (aka Quick Emulator) built with the e1000 NIC emulation support is vulnerable to an infinite loop issue. It could occur while processing data via transmit or receive descriptors, provided the initial receive/transmit descriptor head (TDH/RDH) is set outside the allocated descriptor buffer. A privileged user inside guest could use this flaw to crash the QEMU instance resulting in DoS.

Summary
The virtio_net_load function in hw/net/virtio-net.c in QEMU 1.5.0 through 1.7.x before 1.7.2 allows remote attackers to cause a denial of service or possibly execute arbitrary code via vectors in which the value of curr_queues is greater than max_queues, which triggers an out-of-bounds write.

Summary
The get_cmd function in hw/scsi/esp.c in the 53C9X Fast SCSI Controller (FSC) support in QEMU does not properly check DMA length, which allows local guest OS administrators to cause a denial of service (out-of-bounds write and QEMU process crash) via unspecified vectors, involving an SCSI command.

Summary
A NULL pointer dereference flaw was found in the megasas-gen2 SCSI host bus adapter emulation of QEMU in versions before and including 6.0. This issue occurs in the megasas_command_cancelled() callback function while dropping a SCSI request. This flaw allows a privileged guest user to crash the QEMU process on the host, resulting in a denial of service. The highest threat from this vulnerability is to system availability.

Summary
QEMU (aka Quick Emulator) built with the TPR optimization for 32-bit Windows guests support is vulnerable to a null pointer dereference flaw. It occurs while doing I/O port write operations via hmp interface. In that, 'current_cpu' remains null, which leads to the null pointer dereference. A user or process could use this flaw to crash the QEMU instance, resulting in DoS issue.

Summary
The qdisk PV disk backend in qemu-xen in Xen 4.2.x and 4.3.x before 4.3.1, and qemu 1.1 and other versions, allows local HVM guests to cause a denial of service (domain grant reference consumption) via unspecified vectors.

Summary
The sdhci_sdma_transfer_multi_blocks function in hw/sd/sdhci.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (out-of-bounds heap access and crash) or execute arbitrary code on the QEMU host via vectors involving the data transfer length.

Summary
An out-of-bounds write flaw was found in the UAS (USB Attached SCSI) device emulation of QEMU in versions prior to 6.2.0-rc0. The device uses the guest supplied stream number unchecked, which can lead to out-of-bounds access to the UASDevice->data3 and UASDevice->status3 fields. A malicious guest user could use this flaw to crash QEMU or potentially achieve code execution with the privileges of the QEMU process on the host.

Summary
A use-after-free flaw was found in the MegaRAID emulator of QEMU. This issue occurs while processing SCSI I/O requests in the case of an error mptsas_free_request() that does not dequeue the request object 'req' from a pending requests queue. This flaw allows a privileged guest user to crash the QEMU process on the host, resulting in a denial of service. Versions between 2.10.0 and 5.2.0 are potentially affected.

Summary
Heap-based buffer overflow in the Cirrus VGA implementation in (1) KVM before kvm-82 and (2) QEMU on Debian GNU/Linux and Ubuntu might allow local users to gain privileges by using the VNC console for a connection, aka the LGD-54XX "bitblt" heap overflow. NOTE: this issue exists because of an incorrect fix for CVE-2007-1320.

Summary
An integer overflow was found in QEMU 4.0.1 through 4.2.0 in the way it implemented ATI VGA emulation. This flaw occurs in the ati_2d_blt() routine in hw/display/ati-2d.c while handling MMIO write operations through the ati_mm_write() callback. A malicious guest could abuse this flaw to crash the QEMU process, resulting in a denial of service.

Summary
QEMU (aka Quick Emulator) built with the Rocker switch emulation support is vulnerable to an off-by-one error. It happens while processing transmit (tx) descriptors in 'tx_consume' routine, if a descriptor was to have more than allowed (ROCKER_TX_FRAGS_MAX=16) fragments. A privileged user inside guest could use this flaw to cause memory leakage on the host or crash the QEMU process instance resulting in DoS issue.

Summary
QEMU (aka Quick Emulator) built with an IDE AHCI emulation support is vulnerable to a null pointer dereference flaw. It occurs while unmapping the Frame Information Structure (FIS) and Command List Block (CLB) entries. A privileged user inside guest could use this flaw to crash the QEMU process instance resulting in DoS.

Summary
An issue was discovered in QEMU through 5.1.0. An out-of-bounds memory access was found in the ATI VGA device implementation. This flaw occurs in the ati_2d_blt() routine in hw/display/ati_2d.c while handling MMIO write operations through the ati_mm_write() callback. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service.

Summary
A flaw was found in the QXL display device emulation in QEMU. An integer overflow in the cursor_alloc() function can lead to the allocation of a small cursor object followed by a subsequent heap-based buffer overflow. This flaw allows a malicious privileged guest user to crash the QEMU process on the host or potentially execute arbitrary code within the context of the QEMU process.

Vulnerability from variot
The pit_ioport_read in i8254.c in the Linux kernel before 2.6.33 and QEMU before 2.3.1 does not distinguish between read lengths and write lengths, which might allow guest OS users to execute arbitrary code on the host OS by triggering use of an invalid index. QEMU is prone to a memory-corruption vulnerability because it fails to perform adequate boundary-checks on user-supplied data. An attacker can exploit this issue to execute arbitrary code on the host with the privileges of the hosting QEMU process. Failed exploit attempts may result in a denial-of-service condition. The Linux kernel is the kernel used by the open source operating system Linux released by the American Linux Foundation. The NFSv4 implementation is one of the distributed file system protocols. QEMU (also known as Quick Emulator) is a set of analog processor software developed by French programmer Fabrice Bellard. The software has the characteristics of fast speed and cross-platform. There is a security vulnerability in the 'pit_ioport_read' function in the i8254.c file of Linux kernel 2.6.32 and earlier versions and QEMU 2.3.0 and earlier versions. The vulnerability is due to the fact that the program does not distinguish between read length and write length. Relevant releases/architectures:

Synopsis: Important: qemu-kvm security and bug fix update Advisory ID: RHSA-2015:1507-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2015-1507.html Issue date: 2015-07-27 CVE Names: CVE-2015-3214 CVE-2015-5154 =====================================================================
- Summary:
Updated qemu-kvm packages that fix two security issues and one bug are now available for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.
- Relevant releases/architectures:
Red Hat Enterprise Linux Client (v. 7) - x86_64 Red Hat Enterprise Linux Client Optional (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode Optional (v. 7) - x86_64 Red Hat Enterprise Linux Server (v. 7) - ppc64, x86_64 Red Hat Enterprise Linux Server Optional (v. 7) - ppc64, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - x86_64 Red Hat Enterprise Linux Workstation Optional (v. 7) - x86_64
- Description:
KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on AMD64 and Intel 64 systems. The qemu-kvm package provides the user-space component for running virtual machines using KVM.
A heap buffer overflow flaw was found in the way QEMU's IDE subsystem handled I/O buffer access while processing certain ATAPI commands. (CVE-2015-5154)
An out-of-bounds memory access flaw, leading to memory corruption or possibly an information leak, was found in QEMU's pit_ioport_read() function. (CVE-2015-3214)
Red Hat would like to thank Matt Tait of Google's Project Zero security team for reporting the CVE-2015-3214 issue. The CVE-2015-5154 issue was discovered by Kevin Wolf of Red Hat.
This update also fixes the following bug:
- Due to an incorrect implementation of portable memory barriers, the QEMU emulator in some cases terminated unexpectedly when a virtual disk was under heavy I/O load. This update fixes the implementation in order to achieve correct synchronization between QEMU's threads. As a result, the described crash no longer occurs. (BZ#1233643)
All qemu-kvm users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing this update, shut down all running virtual machines. Once all virtual machines have shut down, start them again for this update to take effect.
- Solution:
Before applying this update, make sure all previously released errata relevant to your system have been applied.
For details on how to apply this update, refer to:

"data": "The pit_ioport_read in i8254.c in the Linux kernel before 2.6.33 and QEMU before 2.3.1 does not distinguish between read lengths and write lengths, which might allow guest OS users to execute arbitrary code on the host OS by triggering use of an invalid index. QEMU is prone to a memory-corruption vulnerability because it fails to perform adequate boundary-checks on user-supplied data. \nAn attacker can exploit this issue to execute arbitrary code on the host with the privileges of the hosting QEMU process. Failed exploit attempts may result in a denial-of-service condition. The Linux kernel is the kernel used by the open source operating system Linux released by the American Linux Foundation. The NFSv4 implementation is one of the distributed file system protocols. QEMU (also known as Quick Emulator) is a set of analog processor software developed by French programmer Fabrice Bellard. The software has the characteristics of fast speed and cross-platform. There is a security vulnerability in the \u0027pit_ioport_read\u0027 function in the i8254.c file of Linux kernel 2.6.32 and earlier versions and QEMU 2.3.0 and earlier versions. The vulnerability is due to the fact that the program does not distinguish between read length and write length.

Summary:\n\nUpdated qemu-kvm packages that fix two security issues and one bug are now\navailable for Red Hat Enterprise Linux 7. \n\nRed Hat Product Security has rated this update as having Important security\nimpact. Common Vulnerability Scoring System (CVSS) base scores, which give\ndetailed severity ratings, are available for each vulnerability from the\nCVE links in the References section. \n\n2. Relevant releases/architectures:\n\nRed Hat Enterprise Linux Client (v. 7) - x86_64\nRed Hat Enterprise Linux Client Optional (v. 7) - x86_64\nRed Hat Enterprise Linux ComputeNode Optional (v. 7) - x86_64\nRed Hat Enterprise Linux Server (v. 7) - ppc64, x86_64\nRed Hat Enterprise Linux Server Optional (v. 7) - ppc64, x86_64\nRed Hat Enterprise Linux Workstation (v. 7) - x86_64\nRed Hat Enterprise Linux Workstation Optional (v. 7) - x86_64\n\n3. Description:\n\nKVM (Kernel-based Virtual Machine) is a full virtualization solution for\nLinux on AMD64 and Intel 64 systems. The qemu-kvm package provides the\nuser-space component for running virtual machines using KVM. \n\nA heap buffer overflow flaw was found in the way QEMU\u0027s IDE subsystem\nhandled I/O buffer access while processing certain ATAPI commands. \n(CVE-2015-5154)\n\nAn out-of-bounds memory access flaw, leading to memory corruption or\npossibly an information leak, was found in QEMU\u0027s pit_ioport_read()\nfunction. (CVE-2015-3214)\n\nRed Hat would like to thank Matt Tait of Google\u0027s Project Zero security\nteam for reporting the CVE-2015-3214 issue. The CVE-2015-5154 issue was\ndiscovered by Kevin Wolf of Red Hat. \n\nThis update also fixes the following bug:\n\n* Due to an incorrect implementation of portable memory barriers, the QEMU\nemulator in some cases terminated unexpectedly when a virtual disk was\nunder heavy I/O load. This update fixes the implementation in order to\nachieve correct synchronization between QEMU\u0027s threads. As a result, the\ndescribed crash no longer occurs. (BZ#1233643)\n\nAll qemu-kvm users are advised to upgrade to these updated packages, which\ncontain backported patches to correct these issues. After installing this\nupdate, shut down all running virtual machines. Once all virtual machines\nhave shut down, start them again for this update to take effect. \n\n4. Solution:\n\nBefore applying this update, make sure all previously released errata\nrelevant to your system have been applied. \n\nFor details on how to apply this update, refer to:\n\nhttps://access.redhat.com/articles/11258\n\n5.

Vulnerability from variot
Heap-based buffer overflow in the PCNET controller in QEMU allows remote attackers to execute arbitrary code by sending a packet with TXSTATUS_STARTPACKET set and then a crafted packet with TXSTATUS_DEVICEOWNS set. Xen is a virtualization technology for the Linux kernel that allows multiple operating systems to run simultaneously. QEMU is prone to a heap-based buffer-overflow vulnerability. Failed attacks will cause denial-of-service conditions. QEMU (also known as Quick Emulator) is a set of analog processor software developed by French programmer Fabrice Bellard. The software has the characteristics of fast speed and cross-platform. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1

--roWGDR0oQEDLX1s6lNAQV7ISgI2Pjo8Pc . ============================================================================ Ubuntu Security Notice USN-2630-1 June 10, 2015
qemu, qemu-kvm vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 15.04
- Ubuntu 14.10
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS
Summary:
Several security issues were fixed in QEMU.
Software Description: - qemu: Machine emulator and virtualizer - qemu-kvm: Machine emulator and virtualizer
Details:
Matt Tait discovered that QEMU incorrectly handled the virtual PCNET driver. In the default installation, when QEMU is used with libvirt, attackers would be isolated by the libvirt AppArmor profile. (CVE-2015-3209)
Kurt Seifried discovered that QEMU incorrectly handled certain temporary files. A local attacker could use this issue to cause a denial of service. (CVE-2015-4037)
Jan Beulich discovered that the QEMU Xen code incorrectly restricted write access to the host MSI message data field. A malicious guest could use this issue to cause a denial of service. This issue only applied to Ubuntu 14.04 LTS, Ubuntu 14.10 and Ubuntu 15.04. (CVE-2015-4103)
Jan Beulich discovered that the QEMU Xen code incorrectly restricted access to the PCI MSI mask bits. A malicious guest could use this issue to cause a denial of service. This issue only applied to Ubuntu 14.04 LTS, Ubuntu 14.10 and Ubuntu 15.04. (CVE-2015-4104)
Jan Beulich discovered that the QEMU Xen code incorrectly handled MSI-X error messages. A malicious guest could use this issue to cause a denial of service. This issue only applied to Ubuntu 14.04 LTS, Ubuntu 14.10 and Ubuntu 15.04. (CVE-2015-4105)
Jan Beulich discovered that the QEMU Xen code incorrectly restricted write access to the PCI config space. A malicious guest could use this issue to cause a denial of service, obtain sensitive information, or possibly execute arbitrary code. This issue only applied to Ubuntu 14.04 LTS, Ubuntu 14.10 and Ubuntu 15.04. (CVE-2015-4106)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 15.04: qemu-system 1:2.2+dfsg-5expubuntu9.2 qemu-system-aarch64 1:2.2+dfsg-5expubuntu9.2 qemu-system-arm 1:2.2+dfsg-5expubuntu9.2 qemu-system-mips 1:2.2+dfsg-5expubuntu9.2 qemu-system-misc 1:2.2+dfsg-5expubuntu9.2 qemu-system-ppc 1:2.2+dfsg-5expubuntu9.2 qemu-system-sparc 1:2.2+dfsg-5expubuntu9.2 qemu-system-x86 1:2.2+dfsg-5expubuntu9.2
Ubuntu 14.10: qemu-system 2.1+dfsg-4ubuntu6.7 qemu-system-aarch64 2.1+dfsg-4ubuntu6.7 qemu-system-arm 2.1+dfsg-4ubuntu6.7 qemu-system-mips 2.1+dfsg-4ubuntu6.7 qemu-system-misc 2.1+dfsg-4ubuntu6.7 qemu-system-ppc 2.1+dfsg-4ubuntu6.7 qemu-system-sparc 2.1+dfsg-4ubuntu6.7 qemu-system-x86 2.1+dfsg-4ubuntu6.7
Ubuntu 14.04 LTS: qemu-system 2.0.0+dfsg-2ubuntu1.13 qemu-system-aarch64 2.0.0+dfsg-2ubuntu1.13 qemu-system-arm 2.0.0+dfsg-2ubuntu1.13 qemu-system-mips 2.0.0+dfsg-2ubuntu1.13 qemu-system-misc 2.0.0+dfsg-2ubuntu1.13 qemu-system-ppc 2.0.0+dfsg-2ubuntu1.13 qemu-system-sparc 2.0.0+dfsg-2ubuntu1.13 qemu-system-x86 2.0.0+dfsg-2ubuntu1.13
Ubuntu 12.04 LTS: qemu-kvm 1.0+noroms-0ubuntu14.23

"data": "Heap-based buffer overflow in the PCNET controller in QEMU allows remote attackers to execute arbitrary code by sending a packet with TXSTATUS_STARTPACKET set and then a crafted packet with TXSTATUS_DEVICEOWNS set. Xen is a virtualization technology for the Linux kernel that allows multiple operating systems to run simultaneously. QEMU is prone to a heap-based buffer-overflow vulnerability. Failed attacks will cause denial-of-service conditions. QEMU (also known as Quick Emulator) is a set of analog processor software developed by French programmer Fabrice Bellard. The software has the characteristics of fast speed and cross-platform. -----BEGIN PGP SIGNED MESSAGE-----\nHash: SHA1\n\n=====================================================================\n Red Hat Security Advisory\n\nSynopsis: Important: qemu-kvm security update\nAdvisory ID: RHSA-2015:1087-01\nProduct: Red Hat Enterprise Linux\nAdvisory URL: https://rhn.redhat.com/errata/RHSA-2015-1087.html\nIssue date: 2015-06-10\nCVE Names: CVE-2015-3209 \n=====================================================================\n\n1. Summary:\n\nUpdated qemu-kvm packages that fix one security issue are now available for\nRed Hat Enterprise Linux 6. \n\nRed Hat Product Security has rated this update as having Important security\nimpact. A Common Vulnerability Scoring System (CVSS) base score, which\ngives a detailed severity rating, is available from the CVE link in the\nReferences section. \n\n2. Relevant releases/architectures:\n\nRed Hat Enterprise Linux Desktop (v. 6) - i386, x86_64\nRed Hat Enterprise Linux HPC Node (v. 6) - x86_64\nRed Hat Enterprise Linux Server (v. 6) - i386, x86_64\nRed Hat Enterprise Linux Workstation (v. 6) - i386, x86_64\n\n3. Description:\n\nKVM (Kernel-based Virtual Machine) is a full virtualization solution for\nLinux on AMD64 and Intel 64 systems. The qemu-kvm package provides the\nuser-space component for running virtual machines using KVM. \n\nA flaw was found in the way QEMU\u0027s AMD PCnet Ethernet emulation handled\nmulti-TMD packets with a length above 4096 bytes. (CVE-2015-3209)\n\nRed Hat would like to thank Matt Tait of Google\u0027s Project Zero security\nteam for reporting this issue. \n\nAll qemu-kvm users are advised to upgrade to these updated packages, which\ncontain a backported patch to correct this issue. After installing this\nupdate, shut down all running virtual machines. Once all virtual machines\nhave shut down, start them again for this update to take effect. \n\n4.

In the default installation, when QEMU is used with\nlibvirt, attackers would be isolated by the libvirt AppArmor profile. \n(CVE-2015-3209)\n\nKurt Seifried discovered that QEMU incorrectly handled certain temporary\nfiles. A local attacker could use this issue to cause a denial of service. \n(CVE-2015-4037)\n\nJan Beulich discovered that the QEMU Xen code incorrectly restricted write\naccess to the host MSI message data field. A malicious guest could use this\nissue to cause a denial of service. This issue only applied to Ubuntu 14.04\nLTS, Ubuntu 14.10 and Ubuntu 15.04. (CVE-2015-4103)\n\nJan Beulich discovered that the QEMU Xen code incorrectly restricted access\nto the PCI MSI mask bits. A malicious guest could use this issue to cause a\ndenial of service. This issue only applied to Ubuntu 14.04 LTS, Ubuntu\n14.10 and Ubuntu 15.04. (CVE-2015-4104)\n\nJan Beulich discovered that the QEMU Xen code incorrectly handled MSI-X\nerror messages. A malicious guest could use this issue to cause a denial of\nservice. This issue only applied to Ubuntu 14.04 LTS, Ubuntu 14.10 and\nUbuntu 15.04. (CVE-2015-4105)\n\nJan Beulich discovered that the QEMU Xen code incorrectly restricted write\naccess to the PCI config space. A malicious guest could use this issue to\ncause a denial of service, obtain sensitive information, or possibly\nexecute arbitrary code. This issue only applied to Ubuntu 14.04 LTS,\nUbuntu 14.10 and Ubuntu 15.04. (CVE-2015-4106)\n\nUpdate instructions:\n\nThe problem can be corrected by updating your system to the following\npackage versions:\n\nUbuntu 15.04:\n qemu-system 1:2.2+dfsg-5expubuntu9.2\n qemu-system-aarch64 1:2.2+dfsg-5expubuntu9.2\n qemu-system-arm 1:2.2+dfsg-5expubuntu9.2\n qemu-system-mips 1:2.2+dfsg-5expubuntu9.2\n qemu-system-misc 1:2.2+dfsg-5expubuntu9.2\n qemu-system-ppc 1:2.2+dfsg-5expubuntu9.2\n qemu-system-sparc 1:2.2+dfsg-5expubuntu9.2\n qemu-system-x86 1:2.2+dfsg-5expubuntu9.2\n\nUbuntu 14.10:\n qemu-system 2.1+dfsg-4ubuntu6.7\n qemu-system-aarch64 2.1+dfsg-4ubuntu6.7\n qemu-system-arm 2.1+dfsg-4ubuntu6.7\n qemu-system-mips 2.1+dfsg-4ubuntu6.7\n qemu-system-misc 2.1+dfsg-4ubuntu6.7\n qemu-system-ppc 2.1+dfsg-4ubuntu6.7\n qemu-system-sparc 2.1+dfsg-4ubuntu6.7\n qemu-system-x86 2.1+dfsg-4ubuntu6.7\n\nUbuntu 14.04 LTS:\n qemu-system 2.0.0+dfsg-2ubuntu1.13\n qemu-system-aarch64 2.0.0+dfsg-2ubuntu1.13\n qemu-system-arm 2.0.0+dfsg-2ubuntu1.13\n qemu-system-mips 2.0.0+dfsg-2ubuntu1.13\n qemu-system-misc 2.0.0+dfsg-2ubuntu1.13\n qemu-system-ppc 2.0.0+dfsg-2ubuntu1.13\n qemu-system-sparc 2.0.0+dfsg-2ubuntu1.13\n qemu-system-x86 2.0.0+dfsg-2ubuntu1.13\n\nUbuntu 12.04 LTS:\n qemu-kvm 1.0+noroms-0ubuntu14.23\n\nAfter a standard system update you need to restart all QEMU virtual\nmachines to make all the necessary changes. \n\nhttp://creativecommons.org/licenses/by-sa/2.5\n",

Vulnerability from variot
The Floppy Disk Controller (FDC) in QEMU, as used in Xen 4.5.x and earlier and KVM, allows local guest users to cause a denial of service (out-of-bounds write and guest crash) or possibly execute arbitrary code via the (1) FD_CMD_READ_ID, (2) FD_CMD_DRIVE_SPECIFICATION_COMMAND, or other unspecified commands, aka VENOM. QEMU is prone to a remote memory-corruption vulnerability because the application fails to perform adequate boundary-checks on user-supplied data. An attacker can exploit this issue to execute arbitrary code within the context of the affected application. Failed exploit attempts may result in a denial-of-service condition. Relevant releases/architectures:
RHEV Agents (vdsm) - x86_64
- After installing this update, shut down all running virtual machines.
Background
VirtualBox is a powerful virtualization product from Oracle.

===================================================================== Red Hat Security Advisory
Synopsis: Important: kvm security update Advisory ID: RHSA-2015:1003-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2015-1003.html Issue date: 2015-05-13 CVE Names: CVE-2015-3456 =====================================================================
- Summary:
Updated kvm packages that fix one security issue are now available for Red Hat Enterprise Linux 5.
Red Hat Product Security has rated this update as having Important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.
- Relevant releases/architectures:
RHEL Desktop Multi OS (v. 5 client) - x86_64 RHEL Virtualization (v. 5 server) - x86_64
- Description:
KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on AMD64 and Intel 64 systems.
An out-of-bounds memory access flaw was found in the way QEMU's virtual Floppy Disk Controller (FDC) handled FIFO buffer access while processing certain FDC commands. A privileged guest user could use this flaw to crash the guest or, potentially, execute arbitrary code on the host with the privileges of the host's QEMU process corresponding to the guest. (CVE-2015-3456)
Red Hat would like to thank Jason Geffner of CrowdStrike for reporting this issue.
All kvm users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. Note: The procedure in the Solution section must be performed before this update will take effect.
- Solution:
Before applying this update, make sure all previously released errata relevant to your system have been applied.
For details on how to apply this update, refer to:
https://access.redhat.com/articles/11258
The following procedure must be performed before this update will take effect:
1) Stop all KVM guest virtual machines.
2) Either reboot the hypervisor machine or, as the root user, remove (using "modprobe -r [module]") and reload (using "modprobe [module]") all of the following modules which are currently running (determined using "lsmod"): kvm, ksm, kvm-intel or kvm-amd.
3) Restart the KVM guest virtual machines.

CVE-2015-1779
Daniel P. Berrange discovered a denial of service vulnerability in
the VNC web socket decoder.
CVE-2015-2756
Jan Beulich discovered that unmediated PCI command register could
result in denial of service.
CVE-2015-3456
Jason Geffner discovered a buffer overflow in the emulated floppy
disk drive, resulting in the potential execution of arbitrary code.
For the oldstable distribution (wheezy), these problems have been fixed in version 1.1.2+dfsg-6a+deb7u7 of the qemu source package and in version 1.1.2+dfsg-6+deb7u7 of the qemu-kvm source package. Only CVE-2015-3456 affects oldstable.
For the stable distribution (jessie), these problems have been fixed in version 1:2.1+dfsg-12.
For the unstable distribution (sid), these problems will be fixed soon.
We recommend that you upgrade your qemu packages

"data": "The Floppy Disk Controller (FDC) in QEMU, as used in Xen 4.5.x and earlier and KVM, allows local guest users to cause a denial of service (out-of-bounds write and guest crash) or possibly execute arbitrary code via the (1) FD_CMD_READ_ID, (2) FD_CMD_DRIVE_SPECIFICATION_COMMAND, or other unspecified commands, aka VENOM. QEMU is prone to a remote memory-corruption vulnerability because the application fails to perform adequate boundary-checks on user-supplied data. \nAn attacker can exploit this issue to execute arbitrary code within the context of the affected application. Failed exploit attempts may result in a denial-of-service condition. Relevant releases/architectures:\n\nRHEV Agents (vdsm) - x86_64\n\n3. After installing\nthis update, shut down all running virtual machines. \n\nBackground\n==========\n\nVirtualBox is a powerful virtualization product from Oracle. \n\nhttp://creativecommons.org/licenses/by-sa/2.5\n\n. -----BEGIN PGP SIGNED MESSAGE-----\nHash: SHA1\n\n=====================================================================\n Red Hat Security Advisory\n\nSynopsis: Important: kvm security update\nAdvisory ID: RHSA-2015:1003-01\nProduct: Red Hat Enterprise Linux\nAdvisory URL: https://rhn.redhat.com/errata/RHSA-2015-1003.html\nIssue date: 2015-05-13\nCVE Names: CVE-2015-3456 \n=====================================================================\n\n1. Summary:\n\nUpdated kvm packages that fix one security issue are now available for Red\nHat Enterprise Linux 5. \n\nRed Hat Product Security has rated this update as having Important security\nimpact. A Common Vulnerability Scoring System (CVSS) base score, which\ngives a detailed severity rating, is available from the CVE link in the\nReferences section. \n\n2. Relevant releases/architectures:\n\nRHEL Desktop Multi OS (v. 5 client) - x86_64\nRHEL Virtualization (v. 5 server) - x86_64\n\n3. Description:\n\nKVM (Kernel-based Virtual Machine) is a full virtualization solution for\nLinux on AMD64 and Intel 64 systems. \n\nAn out-of-bounds memory access flaw was found in the way QEMU\u0027s virtual\nFloppy Disk Controller (FDC) handled FIFO buffer access while processing\ncertain FDC commands. A privileged guest user could use this flaw to crash\nthe guest or, potentially, execute arbitrary code on the host with the\nprivileges of the host\u0027s QEMU process corresponding to the guest. \n(CVE-2015-3456)\n\nRed Hat would like to thank Jason Geffner of CrowdStrike for reporting\nthis issue. \n\nAll kvm users are advised to upgrade to these updated packages, which\ncontain a backported patch to correct this issue. Note: The procedure in\nthe Solution section must be performed before this update will take effect. \n\n4. Solution:\n\nBefore applying this update, make sure all previously released errata\nrelevant to your system have been applied. \n\nFor details on how to apply this update, refer to:\n\nhttps://access.redhat.com/articles/11258\n\nThe following procedure must be performed before this update will take\neffect:\n\n1) Stop all KVM guest virtual machines. \n\n2) Either reboot the hypervisor machine or, as the root user, remove (using\n\"modprobe -r [module]\") and reload (using \"modprobe [module]\") all of the\nfollowing modules which are currently running (determined using \"lsmod\"):\nkvm, ksm, kvm-intel or kvm-amd. \n\n3) Restart the KVM guest virtual machines. \n\n5.

Vulnerability from variot
The qdisk PV disk backend in qemu-xen in Xen 4.2.x and 4.3.x before 4.3.1, and qemu 1.1 and other versions, allows local HVM guests to cause a denial of service (domain grant reference consumption) via unspecified vectors. Xen is an open source virtual machine monitor developed by the University of Cambridge. Xen 4.2.x, 4.3.x have errors related to mapping authorization references. A domain can be exploited to leak, and then another domain that shares the driver domain is denied service status. Xen is prone to a denial-of-service vulnerability. Successful exploits may allow an attacker to cause a denial-of-service condition. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 201407-03

"data": "The qdisk PV disk backend in qemu-xen in Xen 4.2.x and 4.3.x before 4.3.1, and qemu 1.1 and other versions, allows local HVM guests to cause a denial of service (domain grant reference consumption) via unspecified vectors. Xen is an open source virtual machine monitor developed by the University of Cambridge. Xen 4.2.x, 4.3.x have errors related to mapping authorization references. A domain can be exploited to leak, and then another domain that shares the driver domain is denied service status.
