Summary
The do_insn_fetch function in arch/x86/kvm/emulate.c in the x86 emulator in the KVM subsystem in the Linux kernel before 2.6.32-rc8-next-20091125 tries to interpret instructions that contain too many bytes to be valid, which allows guest OS users to cause a denial of service (increased scheduling latency) on the host OS via unspecified manipulations related to SMP support.

Updated kvm packages that fix one security issue and several bugs are now
available for Red Hat Enterprise Linux 5.
This update has been rated as having moderate security impact by the Red
Hat Security Response Team.
Details
KVM (Kernel-based Virtual Machine) is a full virtualization solution for
Linux on AMD64 and Intel 64 systems. KVM is a Linux kernel module built for
the standard Red Hat Enterprise Linux kernel.
On x86 platforms, the do_insn_fetch() function did not limit the amount of
instruction bytes fetched per instruction. Users in guest operating systems
could leverage this flaw to cause large latencies on SMP hosts that could
lead to a local denial of service on the host operating system. This
update fixes this issue by imposing the architecturally-defined 15 byte
length limit for instructions. (CVE-2009-4031)
This update also fixes the following bugs:
* performance problems occurred when using the qcow2 image format with the
qemu-kvm -drive "cache=none" option (the default setting when not specified
otherwise). This could cause guest operating system installations to take
hours. With this update, performance patches have been backported so that
using the qcow2 image format with the "cache=none" option no longer causes
performance issues. (BZ#520693)
* when using the virtual vm8086 mode, bugs in the emulated hardware task
switching implementation may have, in some situations, caused older guest
operating systems to malfunction. (BZ#532031)
* Windows Server 2003 guests (32-bit) with more than 4GB of memory may have
crashed during reboot when using the default qemu-kvm CPU settings.
(BZ#532043)
* with Red Hat Enterprise Virtualization, guests continued to run after
encountering disk read errors. This could have led to their file systems
becoming corrupted (but not the host's), notably in environments that use
networked storage. With this update, the qemu-kvm -drive "werror=stop"
option now applies not only to write errors but also to read errors: When
using this option, guests will pause on disk read and write errors.
By default, guests managed by Red Hat Enterprise Virtualization use the
"werror=stop" option. This option is not used by default for guests managed
by libvirt. (BZ#537334, BZ#540406)
* the para-virtualized block driver (virtio-blk) silently ignored read
errors when accessing disk images. With this update, the driver correctly
signals the read error to the guest. (BZ#537334)
All KVM users should upgrade to these updated packages, which contain
backported patches to resolve these issues. Note: The procedure in the
Solution section must be performed before this update will take effect.

Linux on AMD64 and Intel 64 systems. KVM is a Linux kernel module built for
the standard Red Hat Enterprise Linux kernel.
On x86 platforms, the do_insn_fetch() function did not limit the amount of
instruction bytes fetched per instruction. Users in guest operating systems
could leverage this flaw to cause large latencies on SMP hosts that could
lead to a local denial of service on the host operating system. This
update fixes this issue by imposing the architecturally-defined 15 byte
length limit for instructions. (CVE-2009-4031)
This update also fixes the following bugs:
* performance problems occurred when using the qcow2 image format with the
qemu-kvm -drive "cache=none" option (the default setting when not specified
otherwise). This could cause guest operating system installations to take
hours. With this update, performance patches have been backported so that
using the qcow2 image format with the "cache=none" option no longer causes
performance issues. (BZ#520693)
* when using the virtual vm8086 mode, bugs in the emulated hardware task
switching implementation may have, in some situations, caused older guest
operating systems to malfunction. (BZ#532031)
* Windows Server 2003 guests (32-bit) with more than 4GB of memory may have
crashed during reboot when using the default qemu-kvm CPU settings.
(BZ#532043)
* with Red Hat Enterprise Virtualization, guests continued to run after
encountering disk read errors. This could have led to their file systems
becoming corrupted (but not the host's), notably in environments that use
networked storage. With this update, the qemu-kvm -drive "werror=stop"
option now applies not only to write errors but also to read errors: When
using this option, guests will pause on disk read and write errors.
By default, guests managed by Red Hat Enterprise Virtualization use the
"werror=stop" option. This option is not used by default for guests managed
by libvirt. (BZ#537334, BZ#540406)
* the para-virtualized block driver (virtio-blk) silently ignored read
errors when accessing disk images. With this update, the driver correctly
signals the read error to the guest. (BZ#537334)
All KVM users should upgrade to these updated packages, which contain
backported patches to resolve these issues. Note: The procedure in the
Solution section must be performed before this update will take effect.

Details
KVM (Kernel-based Virtual Machine) is a full virtualization solution for
Linux on AMD64 and Intel 64 systems. KVM is a Linux kernel module built for
the standard Red Hat Enterprise Linux kernel.
On x86 platforms, the do_insn_fetch() function did not limit the amount of
instruction bytes fetched per instruction. Users in guest operating systems
could leverage this flaw to cause large latencies on SMP hosts that could
lead to a local denial of service on the host operating system. This
update fixes this issue by imposing the architecturally-defined 15 byte
length limit for instructions. (CVE-2009-4031)
This update also fixes the following bugs:
* performance problems occurred when using the qcow2 image format with the
qemu-kvm -drive "cache=none" option (the default setting when not specified
otherwise). This could cause guest operating system installations to take
hours. With this update, performance patches have been backported so that
using the qcow2 image format with the "cache=none" option no longer causes
performance issues. (BZ#520693)
* when using the virtual vm8086 mode, bugs in the emulated hardware task
switching implementation may have, in some situations, caused older guest
operating systems to malfunction. (BZ#532031)
* Windows Server 2003 guests (32-bit) with more than 4GB of memory may have
crashed during reboot when using the default qemu-kvm CPU settings.
(BZ#532043)
* with Red Hat Enterprise Virtualization, guests continued to run after
encountering disk read errors. This could have led to their file systems
becoming corrupted (but not the host's), notably in environments that use
networked storage. With this update, the qemu-kvm -drive "werror=stop"
option now applies not only to write errors but also to read errors: When
using this option, guests will pause on disk read and write errors.
By default, guests managed by Red Hat Enterprise Virtualization use the
"werror=stop" option. This option is not used by default for guests managed
by libvirt. (BZ#537334, BZ#540406)
* the para-virtualized block driver (virtio-blk) silently ignored read
errors when accessing disk images. With this update, the driver correctly
signals the read error to the guest. (BZ#537334)
All KVM users should upgrade to these updated packages, which contain
backported patches to resolve these issues. Note: The procedure in the
Solution section must be performed before this update will take effect.

Note: RHEV Hypervisor is only available for the Intel 64 and AMD64
architectures with virtualization extensions.
A flaw was found in the Realtek r8169 Ethernet driver in the Linux kernel.
pci_unmap_single() presented a memory leak that could lead to IOMMU space
exhaustion and a system crash. An attacker on the local network could
trigger this flaw by using jumbo frames for large amounts of network
traffic. (CVE-2009-3613)
On x86 platforms, the do_insn_fetch() function did not limit the amount of
instruction bytes fetched per instruction. Users in guest operating systems
could leverage this flaw to cause large latencies on SMP hosts that could
lead to a local denial of service on the host operating system. This update
fixes this issue by imposing the architecturally-defined 15 byte length
limit for instructions. (CVE-2009-4031)
This updated package provides updated components that include fixes for
security issues; however, these issues have no security impact for RHEV
Hypervisor. These fixes are for kernel issues CVE-2009-2695, CVE-2009-2908,
CVE-2009-3228, CVE-2009-3286, CVE-2009-3547, CVE-2009-3612, CVE-2009-3620,
CVE-2009-3621, and CVE-2009-3726; acpid issue CVE-2009-4033; expat issues
CVE-2009-3560 and CVE-2009-3720; and wget issue CVE-2009-3490.
This update also fixes the following bugs:
* the scsi_dh_rdac driver was updated to recognize the Sun StorageTek
Flexline 380. This driver is now also loaded into initrd to handle passive
paths correctly. Without this initrd change, lots of errors could occur
during boot, increasing boot time. (BZ#545909)
* during the firstboot network configuration of the RHEV Hypervisor, it was
only possible to specify NTP servers by their IP addresses if the RHEV
Hypervisor system was configured with a static IP address. With this
update, hostnames can also be used to specify NTP servers. (BZ#545923)
* with the default settings, performance problems occurred when using the
qcow2 image format. This could cause guest operating system installations
to take hours. With this update, performance patches have been backported
to resolve this issue. (BZ#520693)
* when using the virtual vm8086 mode, bugs in the emulated hardware task
switching implementation may have, in some situations, caused older guest
operating systems to malfunction. (BZ#532031)
* Windows Server 2003 guests (32-bit) with more than 4GB of memory may have
crashed during reboot when using the default RHEV Hypervisor settings.
(BZ#532043)
* guests continued to run after encountering disk read errors. This could
have led to their file systems becoming corrupted (but not the host's),
notably in environments that use networked storage. With this update,
guests will now pause on disk read and write errors. (BZ#537334, BZ#540406)
* the para-virtualized block driver (virtio-blk) silently ignored read
errors when accessing disk images. With this update, the driver correctly
signals the read error to the guest. (BZ#537334)
Users of the Red Hat Enterprise Virtualization Hypervisor are advised to
upgrade to this updated package, which corrects these issues.

Summary
Red Hat Security Advisory: rhev-hypervisor security and bug fix update
Notes
Topic
An updated rhev-hypervisor package that fixes security issues and several
bugs is now available.
This update has been rated as having important security impact by the Red
Hat Security Response Team.
Details
The rhev-hypervisor package provides a Red Hat Enterprise Virtualization
(RHEV) Hypervisor ISO disk image. The RHEV Hypervisor is a dedicated
Kernel-based Virtual Machine (KVM) hypervisor. It includes everything
necessary to run and manage virtual machines: A subset of the Red Hat
Enterprise Linux operating environment and the Red Hat Enterprise
Virtualization Agent.
Note: RHEV Hypervisor is only available for the Intel 64 and AMD64
architectures with virtualization extensions.
A flaw was found in the Realtek r8169 Ethernet driver in the Linux kernel.
pci_unmap_single() presented a memory leak that could lead to IOMMU space
exhaustion and a system crash. An attacker on the local network could
trigger this flaw by using jumbo frames for large amounts of network
traffic. (CVE-2009-3613)
On x86 platforms, the do_insn_fetch() function did not limit the amount of
instruction bytes fetched per instruction. Users in guest operating systems
could leverage this flaw to cause large latencies on SMP hosts that could
lead to a local denial of service on the host operating system. This update
fixes this issue by imposing the architecturally-defined 15 byte length
limit for instructions. (CVE-2009-4031)
This updated package provides updated components that include fixes for
security issues; however, these issues have no security impact for RHEV
Hypervisor. These fixes are for kernel issues CVE-2009-2695, CVE-2009-2908,
CVE-2009-3228, CVE-2009-3286, CVE-2009-3547, CVE-2009-3612, CVE-2009-3620,
CVE-2009-3621, and CVE-2009-3726; acpid issue CVE-2009-4033; expat issues
CVE-2009-3560 and CVE-2009-3720; and wget issue CVE-2009-3490.
This update also fixes the following bugs:
* the scsi_dh_rdac driver was updated to recognize the Sun StorageTek
Flexline 380. This driver is now also loaded into initrd to handle passive
paths correctly. Without this initrd change, lots of errors could occur
during boot, increasing boot time. (BZ#545909)
* during the firstboot network configuration of the RHEV Hypervisor, it was
only possible to specify NTP servers by their IP addresses if the RHEV
Hypervisor system was configured with a static IP address. With this
update, hostnames can also be used to specify NTP servers. (BZ#545923)
* with the default settings, performance problems occurred when using the
qcow2 image format. This could cause guest operating system installations
to take hours. With this update, performance patches have been backported
to resolve this issue. (BZ#520693)
* when using the virtual vm8086 mode, bugs in the emulated hardware task
switching implementation may have, in some situations, caused older guest
operating systems to malfunction. (BZ#532031)
* Windows Server 2003 guests (32-bit) with more than 4GB of memory may have
crashed during reboot when using the default RHEV Hypervisor settings.
(BZ#532043)
* guests continued to run after encountering disk read errors. This could
have led to their file systems becoming corrupted (but not the host's),
notably in environments that use networked storage. With this update,
guests will now pause on disk read and write errors. (BZ#537334, BZ#540406)
* the para-virtualized block driver (virtio-blk) silently ignored read
errors when accessing disk images. With this update, the driver correctly
signals the read error to the guest. (BZ#537334)
Users of the Red Hat Enterprise Virtualization Hypervisor are advised to
upgrade to this updated package, which corrects these issues.

Summary
Red Hat Security Advisory: rhev-hypervisor security and bug fix update
Notes
Topic
An updated rhev-hypervisor package that fixes security issues and several
bugs is now available.
This update has been rated as having important security impact by the Red
Hat Security Response Team.
Details
The rhev-hypervisor package provides a Red Hat Enterprise Virtualization
(RHEV) Hypervisor ISO disk image. The RHEV Hypervisor is a dedicated
Kernel-based Virtual Machine (KVM) hypervisor. It includes everything
necessary to run and manage virtual machines: A subset of the Red Hat
Enterprise Linux operating environment and the Red Hat Enterprise
Virtualization Agent.
Note: RHEV Hypervisor is only available for the Intel 64 and AMD64
architectures with virtualization extensions.
A flaw was found in the Realtek r8169 Ethernet driver in the Linux kernel.
pci_unmap_single() presented a memory leak that could lead to IOMMU space
exhaustion and a system crash. An attacker on the local network could
trigger this flaw by using jumbo frames for large amounts of network
traffic. (CVE-2009-3613)
On x86 platforms, the do_insn_fetch() function did not limit the amount of
instruction bytes fetched per instruction. Users in guest operating systems
could leverage this flaw to cause large latencies on SMP hosts that could
lead to a local denial of service on the host operating system. This update
fixes this issue by imposing the architecturally-defined 15 byte length
limit for instructions. (CVE-2009-4031)
This updated package provides updated components that include fixes for
security issues; however, these issues have no security impact for RHEV
Hypervisor. These fixes are for kernel issues CVE-2009-2695, CVE-2009-2908,
CVE-2009-3228, CVE-2009-3286, CVE-2009-3547, CVE-2009-3612, CVE-2009-3620,
CVE-2009-3621, and CVE-2009-3726; acpid issue CVE-2009-4033; expat issues
CVE-2009-3560 and CVE-2009-3720; and wget issue CVE-2009-3490.
This update also fixes the following bugs:
* the scsi_dh_rdac driver was updated to recognize the Sun StorageTek
Flexline 380. This driver is now also loaded into initrd to handle passive
paths correctly. Without this initrd change, lots of errors could occur
during boot, increasing boot time. (BZ#545909)
* during the firstboot network configuration of the RHEV Hypervisor, it was
only possible to specify NTP servers by their IP addresses if the RHEV
Hypervisor system was configured with a static IP address. With this
update, hostnames can also be used to specify NTP servers. (BZ#545923)
* with the default settings, performance problems occurred when using the
qcow2 image format. This could cause guest operating system installations
to take hours. With this update, performance patches have been backported
to resolve this issue. (BZ#520693)
* when using the virtual vm8086 mode, bugs in the emulated hardware task
switching implementation may have, in some situations, caused older guest
operating systems to malfunction. (BZ#532031)
* Windows Server 2003 guests (32-bit) with more than 4GB of memory may have
crashed during reboot when using the default RHEV Hypervisor settings.
(BZ#532043)
* guests continued to run after encountering disk read errors. This could
have led to their file systems becoming corrupted (but not the host's),
notably in environments that use networked storage. With this update,
guests will now pause on disk read and write errors. (BZ#537334, BZ#540406)
* the para-virtualized block driver (virtio-blk) silently ignored read
errors when accessing disk images. With this update, the driver correctly
signals the read error to the guest. (BZ#537334)
Users of the Red Hat Enterprise Virtualization Hypervisor are advised to
upgrade to this updated package, which corrects these issues.

These fixes are for kernel issues CVE-2009-2695, CVE-2009-2908,\nCVE-2009-3228, CVE-2009-3286, CVE-2009-3547, CVE-2009-3612, CVE-2009-3620,\nCVE-2009-3621, and CVE-2009-3726; acpid issue CVE-2009-4033; expat issues\nCVE-2009-3560 and CVE-2009-3720; and wget issue CVE-2009-3490.\n\nThis update also fixes the following bugs:\n\n* the scsi_dh_rdac driver was updated to recognize the Sun StorageTek\nFlexline 380. This driver is now also loaded into initrd to handle passive\npaths correctly. Without this initrd change, lots of errors could occur\nduring boot, increasing boot time. (BZ#545909)\n\n* during the firstboot network configuration of the RHEV Hypervisor, it was\nonly possible to specify NTP servers by their IP addresses if the RHEV\nHypervisor system was configured with a static IP address. With this\nupdate, hostnames can also be used to specify NTP servers. (BZ#545923)\n\n* with the default settings, performance problems occurred when using the\nqcow2 image format. This could cause guest operating system installations\nto take hours. With this update, performance patches have been backported\nto resolve this issue. (BZ#520693)\n\n* when using the virtual vm8086 mode, bugs in the emulated hardware task\nswitching implementation may have, in some situations, caused older guest\noperating systems to malfunction. (BZ#532031)\n\n* Windows Server 2003 guests (32-bit) with more than 4GB of memory may have\ncrashed during reboot when using the default RHEV Hypervisor settings.\n(BZ#532043)\n\n* guests continued to run after encountering disk read errors. This could\nhave led to their file systems becoming corrupted (but not the host\u0027s),\nnotably in environments that use networked storage. With this update,\nguests will now pause on disk read and write errors. (BZ#537334, BZ#540406)\n\n* the para-virtualized block driver (virtio-blk) silently ignored read\nerrors when accessing disk images. With this update, the driver correctly\nsignals the read error to the guest. (BZ#537334)\n\nUsers of the Red Hat Enterprise Virtualization Hypervisor are advised to\nupgrade to this updated package, which corrects these issues.", "title": "Details" }, { "category": "legal_disclaimer", "text": "This content is licensed under the Creative Commons Attribution 4.0 International License (https://creativecommons.org/licenses/by/4.0/).
