Summary
Red Hat Security Advisory: rhev-hypervisor security update
Notes
Topic
An updated rhev-hypervisor package that fixes several security issues is
now available.
The Red Hat Security Response Team has rated this update as having moderate
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.
Details
The rhev-hypervisor package provides a Red Hat Enterprise Virtualization
Hypervisor ISO disk image. The Red Hat Enterprise Virtualization 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: Red Hat Enterprise Virtualization Hypervisor is only available for
the Intel 64 and AMD64 architectures with virtualization extensions.
The RHBA-2011:1254 update introduced a regression in the Linux kernel's
Ethernet bridge implementation. If a system had an interface in a bridge,
and an attacker on the local network could send packets to that interface,
they could cause a denial of service on that system. (CVE-2011-2942)
A flaw in the Linux kernel could lead to GRO (Generic Receive Offload)
fields being left in an inconsistent state. An attacker on the local
network could use this flaw to trigger a denial of service. GRO is enabled
by default in all network drivers that support it. (CVE-2011-2723)
The way IPv4 and IPv6 protocol sequence numbers and fragment IDs were
generated could allow a man-in-the-middle attacker to inject packets and
possibly hijack connections. Protocol sequence numbers and fragment IDs are
now more random. (CVE-2011-3188)
Non-member VLAN (virtual LAN) packet handling for interfaces in promiscuous
mode and also using the be2net driver could allow an attacker on the local
network to cause a denial of service. (CVE-2011-3347)
Red Hat would like to thank Brent Meshier for reporting CVE-2011-2723; Dan
Kaminsky for reporting CVE-2011-3188; and Somnath Kotur for reporting
CVE-2011-3347.
This updated package provides updated components that include fixes for
numerous security issues. These issues have no security impact on Red Hat
Enterprise Virtualization Hypervisor itself, however.
The security fixes included in this update address the following CVE
numbers:
CVE-2011-2695, CVE-2011-2699, CVE-2011-3191, CVE-2011-1833, CVE-2011-2496,
CVE-2011-3209, CVE-2011-2484, CVE-2011-3131, CVE-2009-4067, CVE-2011-1160,
and CVE-2011-1585 (kernel issues)
CVE-2011-3378 (rpm issues)
Users of Red Hat Enterprise Virtualization Hypervisor should upgrade to
this updated package, which resolves these issues.

Summary
Red Hat Security Advisory: kernel-rt security and bug fix update
Notes
Topic
Updated kernel-rt packages that fix several security issues and two bugs
are now available for Red Hat Enterprise MRG 2.0.
The Red Hat Security Response Team 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.
Details
The kernel-rt packages contain the Linux kernel, the core of any Linux
operating system.
This update fixes the following security issues:
* A malicious CIFS (Common Internet File System) server could send a
specially-crafted response to a directory read request that would result in
a denial of service or privilege escalation on a system that has a CIFS
share mounted. (CVE-2011-3191, Important)
* The way fragmented IPv6 UDP datagrams over the bridge with UDP
Fragmentation Offload (UFO) functionality on were handled could allow a
remote attacker to cause a denial of service. (CVE-2011-4326, Important)
* GRO (Generic Receive Offload) fields could be left in an inconsistent
state. An attacker on the local network could use this flaw to cause a
denial of service. GRO is enabled by default in all network drivers that
support it. (CVE-2011-2723, Moderate)
* IPv4 and IPv6 protocol sequence number and fragment ID generation could
allow a man-in-the-middle attacker to inject packets and possibly hijack
connections. Protocol sequence numbers and fragment IDs are now more
random. (CVE-2011-3188, Moderate)
* A flaw in the FUSE (Filesystem in Userspace) implementation could allow
a local user in the fuse group who has access to mount a FUSE file system
to cause a denial of service. (CVE-2011-3353, Moderate)
* A flaw in the b43 driver. If a system had an active wireless interface
that uses the b43 driver, an attacker able to send a specially-crafted
frame to that interface could cause a denial of service. (CVE-2011-3359,
Moderate)
* A flaw in the way CIFS shares with DFS referrals at their root were
handled could allow an attacker on the local network, who is able to deploy
a malicious CIFS server, to create a CIFS network share that, when mounted,
would cause the client system to crash. (CVE-2011-3363, Moderate)
* A flaw in the m_stop() implementation could allow a local, unprivileged
user to trigger a denial of service. (CVE-2011-3637, Moderate)
* Flaws in ghash_update() and ghash_final() could allow a local,
unprivileged user to cause a denial of service. (CVE-2011-4081, Moderate)
* A flaw in the key management facility could allow a local, unprivileged
user to cause a denial of service via the keyctl utility. (CVE-2011-4110,
Moderate)
* A flaw in the Journaling Block Device (JBD) could allow a local attacker
to crash the system by mounting a specially-crafted ext3 or ext4 disk.
(CVE-2011-4132, Moderate)
* A flaw in the way memory containing security-related data was handled in
tpm_read() could allow a local, unprivileged user to read the results of a
previously run TPM command. (CVE-2011-1162, Low)
* I/O statistics from the taskstats subsystem could be read without any
restrictions, which could allow a local, unprivileged user to gather
confidential information, such as the length of a password used in a
process. (CVE-2011-2494, Low)
* Flaws in tpacket_rcv() and packet_recvmsg() could allow a local,
unprivileged user to leak information to user-space. (CVE-2011-2898, Low)
Red Hat would like to thank Darren Lavender for reporting CVE-2011-3191;
Brent Meshier for reporting CVE-2011-2723; Dan Kaminsky for reporting
CVE-2011-3188; Yogesh Sharma for reporting CVE-2011-3363; Nick Bowler for
reporting CVE-2011-4081; Peter Huewe for reporting CVE-2011-1162; and
Vasiliy Kulikov of Openwall for reporting CVE-2011-2494.
This update also fixes the following bugs:
* Previously, a mismatch in the build-id of the kernel-rt and the one in
the related debuginfo package caused failures in SystemTap and perf.
(BZ#768413)
* IBM x3650m3 systems were not able to boot the MRG Realtime kernel because
they require a pmcraid driver that was not available. The pmcraid driver is
included in this update. (BZ#753992)
Users should upgrade to these updated packages, which correct these issues.
The system must be rebooted for this update to take effect.

Summary
Red Hat Security Advisory: kernel security, bug fix, and enhancement update
Notes
Topic
Updated kernel packages that fix several security issues, various bugs, and
add one enhancement are now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team 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.
Details
The kernel packages contain the Linux kernel, the core of any Linux
operating system.
This update fixes the following security issues:
* Flaws in the AGPGART driver implementation when handling certain IOCTL
commands could allow a local user to cause a denial of service or escalate
their privileges. (CVE-2011-1745, CVE-2011-2022, Important)
* An integer overflow flaw in agp_allocate_memory() could allow a local
user to cause a denial of service or escalate their privileges.
(CVE-2011-1746, Important)
* A race condition flaw was found in the Linux kernel's eCryptfs
implementation. A local attacker could use the mount.ecryptfs_private
utility to mount (and then access) a directory they would otherwise not
have access to. Note: To correct this issue, the RHSA-2011:1241
ecryptfs-utils update, which provides the user-space part of the fix, must
also be installed. (CVE-2011-1833, Moderate)
* A denial of service flaw was found in the way the taskstats subsystem
handled the registration of process exit handlers. A local, unprivileged
user could register an unlimited amount of these handlers, leading to
excessive CPU time and memory use. (CVE-2011-2484, Moderate)
* A flaw was found in the way mapping expansions were handled. A local,
unprivileged user could use this flaw to cause a wrapping condition,
triggering a denial of service. (CVE-2011-2496, Moderate)
* A flaw was found in the Linux kernel's Performance Events implementation.
It could falsely lead the NMI (Non-Maskable Interrupt) Watchdog to detect a
lockup and panic the system. A local, unprivileged user could use this flaw
to cause a denial of service (kernel panic) using the perf tool.
(CVE-2011-2521, Moderate)
* A flaw in skb_gro_header_slow() in the Linux kernel could lead to GRO
(Generic Receive Offload) fields being left in an inconsistent state. An
attacker on the local network could use this flaw to trigger a denial of
service. GRO is enabled by default in all network drivers that support it.
(CVE-2011-2723, Moderate)
* A flaw was found in the way the Linux kernel's Performance Events
implementation handled PERF_COUNT_SW_CPU_CLOCK counter overflow. A local,
unprivileged user could use this flaw to cause a denial of service.
(CVE-2011-2918, Moderate)
* A flaw was found in the Linux kernel's Trusted Platform Module (TPM)
implementation. A local, unprivileged user could use this flaw to leak
information to user-space. (CVE-2011-1160, Low)
* Flaws were found in the tpacket_rcv() and packet_recvmsg() functions in
the Linux kernel. A local, unprivileged user could use these flaws to leak
information to user-space. (CVE-2011-2898, Low)

Summary
Red Hat Security Advisory: kernel security and bug fix update
Notes
Topic
Updated kernel packages that fix one security issue and several bugs are
now available for Red Hat Enterprise Linux 5.6 Extended Update Support.
The Red Hat Security Response Team has rated this update as having moderate
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.
Details
The kernel packages contain the Linux kernel.
Security fix:
* A flaw in skb_gro_header_slow() in the Linux kernel could lead to GRO
(Generic Receive Offload) fields being left in an inconsistent state. An
attacker on the local network could use this flaw to trigger a denial of
service. (CVE-2011-2723, Moderate)
Red Hat would like to thank Brent Meshier for reporting this issue.
Bug fixes:
* When reading a file from a subdirectory in /proc/bus/pci/ while
hot-unplugging the device related to that file, the system will crash. Now,
the kernel correctly handles the simultaneous removal of a device and
access to the representation of that device in the proc file system.
(BZ#713454)
* RHSA-2011:0017 introduced a regression: Non-disk SCSI devices (except for
tape drives) such as enclosure or CD-ROM devices were hidden when attached
to a SAS based RAID controller that uses the megaraid_sas driver. With this
update, such devices are accessible, as expected. (BZ#726487)
* The fix for CVE-2010-3432 provided in RHSA-2011:0004 introduced a
regression: Information in sctp_packet_config(), which was called before
appending data chunks to a packet, was not reset, causing considerably poor
SCTP (Stream Control Transmission Protocol) performance. With this update,
the packet information is reset after transmission. (BZ#727591)
* Certain systems do not correctly set the ACPI FADT APIC mode bit. They
set the bit to "cluster" mode instead of "physical" mode which caused these
systems to boot without the TSC (Time Stamp Counter). With this update, the
ACPI FADT check has been removed due to its unreliability. (BZ#728162)
* Performance when invalidating and rereading cached data as a glock moves
around the cluster with GFS2 is improved. (BZ#729082)
* Performance issues occurred when multiple nodes attempted to call mmap()
on the same inode at the same time on a GFS2 file system, as it was using
an exclusive glock. With this update, a shared lock is used when "noatime"
is set on the mount, allowing mmap() operations to occur in parallel,
fixing this bug. Note that this issue only refers to mmap() system calls,
and not to subsequent page faults. (BZ#729090)
* Some of the functions in the GFS2 file system were not reserving enough
space for the resource group header in a transaction and for resource
groups bit blocks that get added when a memory allocation is performed.
That resulted in failed write and allocation operations. With this update,
GFS2 makes sure to reserve space in the described scenario, using the new
gfs2_rg_blocks() inline function. (BZ#729092)
* When GFS2 grew the file system, it never reread the rindex file during
the grow. This is necessary for large grows when the file system is almost
full, and GFS2 needs to use some of the space allocated earlier in the grow
to complete it. Now, if GFS2 fails to reserve the necessary space and the
rindex data is not up-to-date, it rereads it. (BZ#729094)
* Previously, when the Xen hypervisor split a 2 MB page into 4 KB pages, it
linked the new page from PDE (Page Directory Entry) before it filled
entries of the page with appropriate data. Consequently, when doing a live
migration with EPT (Extended Page Tables) enabled on a non-idle guest
running with more than two virtual CPUs, the guest often terminated
unexpectedly. With this update, the Xen hypervisor prepares the page table
entry first, and then links it in. (BZ#730684)
* Changes made to TSC as a clock source for IRQs caused virtual machines
running under the VMware ESX or ESXi hypervisors to become unresponsive
during the initial kernel boot process. With this update, the
enable_tsc_timer flag enables the do_timer_tsc_timekeeping() function to be
called in the do_timer_interrupt_hook() function, preventing a deadlock in
the timer interrupt handler. (BZ#730688)
Users should upgrade to these updated packages, which contain backported
patches to correct these issues. The system must be rebooted for this
update to take effect.

A Common Vulnerability Scoring System (CVSS) base score,\nwhich gives a detailed severity rating, is available from the CVE link in\nthe References section.", "title": "Topic" }, { "category": "general", "text": "The kernel packages contain the Linux kernel.\n\nSecurity fix:\n\n* A flaw in skb_gro_header_slow() in the Linux kernel could lead to GRO\n(Generic Receive Offload) fields being left in an inconsistent state. An\nattacker on the local network could use this flaw to trigger a denial of\nservice. (CVE-2011-2723, Moderate)\n\nRed Hat would like to thank Brent Meshier for reporting this issue.\n\nBug fixes:\n\n* When reading a file from a subdirectory in /proc/bus/pci/ while\nhot-unplugging the device related to that file, the system will crash. Now,\nthe kernel correctly handles the simultaneous removal of a device and\naccess to the representation of that device in the proc file system.\n(BZ#713454)\n\n* RHSA-2011:0017 introduced a regression: Non-disk SCSI devices (except for\ntape drives) such as enclosure or CD-ROM devices were hidden when attached\nto a SAS based RAID controller that uses the megaraid_sas driver. With this\nupdate, such devices are accessible, as expected. (BZ#726487)\n\n* The fix for CVE-2010-3432 provided in RHSA-2011:0004 introduced a\nregression: Information in sctp_packet_config(), which was called before\nappending data chunks to a packet, was not reset, causing considerably poor\nSCTP (Stream Control Transmission Protocol) performance. With this update,\nthe packet information is reset after transmission. (BZ#727591)\n\n* Certain systems do not correctly set the ACPI FADT APIC mode bit. They\nset the bit to \"cluster\" mode instead of \"physical\" mode which caused these\nsystems to boot without the TSC (Time Stamp Counter). With this update, the\nACPI FADT check has been removed due to its unreliability. (BZ#728162)\n\n* Performance when invalidating and rereading cached data as a glock moves\naround the cluster with GFS2 is improved. (BZ#729082)\n\n* Performance issues occurred when multiple nodes attempted to call mmap()\non the same inode at the same time on a GFS2 file system, as it was using\nan exclusive glock. With this update, a shared lock is used when \"noatime\"\nis set on the mount, allowing mmap() operations to occur in parallel,\nfixing this bug. Note that this issue only refers to mmap() system calls,\nand not to subsequent page faults. (BZ#729090)\n\n* Some of the functions in the GFS2 file system were not reserving enough\nspace for the resource group header in a transaction and for resource\ngroups bit blocks that get added when a memory allocation is performed.\nThat resulted in failed write and allocation operations. With this update,\nGFS2 makes sure to reserve space in the described scenario, using the new\ngfs2_rg_blocks() inline function. (BZ#729092)\n\n* When GFS2 grew the file system, it never reread the rindex file during\nthe grow. This is necessary for large grows when the file system is almost\nfull, and GFS2 needs to use some of the space allocated earlier in the grow\nto complete it. Now, if GFS2 fails to reserve the necessary space and the\nrindex data is not up-to-date, it rereads it. (BZ#729094)\n\n* Previously, when the Xen hypervisor split a 2 MB page into 4 KB pages, it\nlinked the new page from PDE (Page Directory Entry) before it filled\nentries of the page with appropriate data. Consequently, when doing a live\nmigration with EPT (Extended Page Tables) enabled on a non-idle guest\nrunning with more than two virtual CPUs, the guest often terminated\nunexpectedly. With this update, the Xen hypervisor prepares the page table\nentry first, and then links it in. (BZ#730684)\n\n* Changes made to TSC as a clock source for IRQs caused virtual machines\nrunning under the VMware ESX or ESXi hypervisors to become unresponsive\nduring the initial kernel boot process. With this update, the\nenable_tsc_timer flag enables the do_timer_tsc_timekeeping() function to be\ncalled in the do_timer_interrupt_hook() function, preventing a deadlock in\nthe timer interrupt handler. (BZ#730688)\n\nUsers should upgrade to these updated packages, which contain backported\npatches to correct these issues. The system must be rebooted for this\nupdate to take effect.", "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/).

Summary
Red Hat Security Advisory: kernel security, bug fix, and enhancement update
Notes
Topic
Updated kernel packages that fix multiple security issues, several bugs,
and add one enhancement are now available for Red Hat Enterprise Linux 5.
The Red Hat Security Response Team 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.
Details
The kernel packages contain the Linux kernel, the core of any Linux
operating system.
Security fixes:
* The maximum file offset handling for ext4 file systems could allow a
local, unprivileged user to cause a denial of service. (CVE-2011-2695,
Important)
* IPv6 fragment identification value generation could allow a remote
attacker to disrupt a target system's networking, preventing legitimate
users from accessing its services. (CVE-2011-2699, Important)
* A malicious CIFS (Common Internet File System) server could send a
specially-crafted response to a directory read request that would result in
a denial of service or privilege escalation on a system that has a CIFS
share mounted. (CVE-2011-3191, Important)
* A local attacker could use mount.ecryptfs_private to mount (and then
access) a directory they would otherwise not have access to. Note: To
correct this issue, the RHSA-2011:1241 ecryptfs-utils update must also be
installed. (CVE-2011-1833, Moderate)
* A flaw in the taskstats subsystem could allow a local, unprivileged user
to cause excessive CPU time and memory use. (CVE-2011-2484, Moderate)
* Mapping expansion handling could allow a local, unprivileged user to
cause a denial of service. (CVE-2011-2496, Moderate)
* GRO (Generic Receive Offload) fields could be left in an inconsistent
state. An attacker on the local network could use this flaw to cause a
denial of service. GRO is enabled by default in all network drivers that
support it. (CVE-2011-2723, Moderate)
* RHSA-2011:1065 introduced a regression in the Ethernet bridge
implementation. If a system had an interface in a bridge, and an attacker
on the local network could send packets to that interface, they could cause
a denial of service on that system. Xen hypervisor and KVM (Kernel-based
Virtual Machine) hosts often deploy bridge interfaces. (CVE-2011-2942,
Moderate)
* A flaw in the Xen hypervisor IOMMU error handling implementation could
allow a privileged guest user, within a guest operating system that has
direct control of a PCI device, to cause performance degradation on the
host and possibly cause it to hang. (CVE-2011-3131, Moderate)
* IPv4 and IPv6 protocol sequence number and fragment ID generation could
allow a man-in-the-middle attacker to inject packets and possibly hijack
connections. Protocol sequence number and fragment IDs are now more random.
(CVE-2011-3188, Moderate)
* A flaw in the kernel's clock implementation could allow a local,
unprivileged user to cause a denial of service. (CVE-2011-3209, Moderate)
* Non-member VLAN (virtual LAN) packet handling for interfaces in
promiscuous mode and also using the be2net driver could allow an attacker
on the local network to cause a denial of service. (CVE-2011-3347,
Moderate)
* A flaw in the auerswald USB driver could allow a local, unprivileged user
to cause a denial of service or escalate their privileges by inserting a
specially-crafted USB device. (CVE-2009-4067, Low)
* A flaw in the Trusted Platform Module (TPM) implementation could allow a
local, unprivileged user to leak information to user space. (CVE-2011-1160,
Low)
* A local, unprivileged user could possibly mount a CIFS share that
requires authentication without knowing the correct password if the mount
was already mounted by another local user. (CVE-2011-1585, Low)
