"From Red Hat Security Advisory 2010:0088 :

Updated kvm packages that fix multiple security issues and several
bugs are now available for Red Hat Enterprise Linux 5.

This update has been rated as having important security impact by the
Red Hat Security Response Team.

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.

The x86 emulator implementation was missing a check for the Current
Privilege Level (CPL) and I/O Privilege Level (IOPL). A user in a
guest could leverage these flaws to cause a denial of service (guest
crash) or possibly escalate their privileges within that guest.
(CVE-2010-0298, CVE-2010-0306)

A flaw was found in the Programmable Interval Timer (PIT) emulation.
Access to the internal data structure pit_state, which represents the
data state of the emulated PIT, was not properly validated in the
pit_ioport_read() function. A privileged guest user could use this
flaw to crash the host. (CVE-2010-0309)

A flaw was found in the USB passthrough handling code. A specially
crafted USB packet sent from inside a guest could be used to trigger a
buffer overflow in the usb_host_handle_control() function, which runs
under the QEMU-KVM context on the host. A user in a guest could
leverage this flaw to cause a denial of service (guest hang or crash)
or possibly escalate their privileges within the host. (CVE-2010-0297)

This update also fixes the following bugs :

* pvclock MSR values were not preserved during remote migration,
causing time drift for guests. (BZ#537028)

* SMBIOS table 4 data is now generated for Windows guests. (BZ#545874)

* if the qemu-kvm '-net user' option was used, unattended Windows XP
installations did not receive an IP address after reboot. (BZ#546562)

* when being restored from migration, a race condition caused Windows
Server 2008 R2 guests to hang during shutdown. (BZ#546563)

* the kernel symbol checking on the kvm-kmod build process has a
safety check for ABI changes. (BZ#547293)

* on hosts without high-res timers, Windows Server 2003 guests
experienced significant time drift. (BZ#547625)

* in some situations, installing Windows Server 2008 R2 from an ISO
image resulted in a blue screen 'BAD_POOL_HEADER' stop error.
(BZ#548368)

* a bug in the grow_refcount_table() error handling caused infinite
recursion in some cases. This caused the qemu-kvm process to hang and
eventually crash. (BZ#552159)

* for Windows Server 2003 R2, Service Pack 2, 32-bit guests, an
'unhandled vm exit' error could occur during reboot on some systems.
(BZ#552518)

* for Windows guests, QEMU could attempt to stop a stopped audio
device, resulting in a 'snd_playback_stop: ASSERT
playback_channel->base.active failed' error. (BZ#552519)

* the Hypercall driver did not reset the device on power-down.
(BZ#552528)

* mechanisms have been added to make older savevm versions to be
emitted in some cases. (BZ#552529)

* an error in the Makefile prevented users from using the source RPM
to install KVM. (BZ#552530)

* guests became unresponsive and could use up to 100% CPU when running
certain benchmark tests with more than 7 guests running
simultaneously. (BZ#553249)

* QEMU could terminate randomly with virtio-net and SMP enabled.
(BZ#561022)

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."

"Several vulnerabilities have been discovered in the Linux kernel that
may lead to a denial of service, sensitive memory leak or privilege
escalation. The Common Vulnerabilities and Exposures project
identifies the following problems :

  - CVE-2009-3939
    Joseph Malicki reported that the dbg_lvl sysfs attribute
    for the megaraid_sas device driver had world-writable
    permissions, permitting local users to modify logging
    settings.

  - CVE-2009-4027
    Lennert Buytenhek reported a race in the mac80211
    subsystem that may allow remote users to cause a denial
    of service (system crash) on a system connected to the
    same wireless network.

  - CVE-2009-4536 CVE-2009-4538
    Fabian Yamaguchi reported issues in the e1000 and e1000e
    drivers for Intel gigabit network adapters which allow
    remote users to bypass packet filters using specially
    crafted ethernet frames.

  - CVE-2010-0003
    Andi Kleen reported a defect which allows local users to
    gain read access to memory reachable by the kernel when
    the print-fatal-signals option is enabled. This option
    is disabled by default.

  - CVE-2010-0007
    Florian Westphal reported a lack of capability checking
    in the ebtables netfilter subsystem. If the ebtables
    module is loaded, local users can add and modify
    ebtables rules.

  - CVE-2010-0291
    Al Viro reported several issues with the mmap/mremap
    system calls that allow local users to cause a denial of
    service (system panic) or obtain elevated privileges.

  - CVE-2010-0298 & CVE-2010-0306
    Gleb Natapov discovered issues in the KVM subsystem
    where missing permission checks (CPL/IOPL) permit a user
    in a guest system to denial of service a guest (system
    crash) or gain escalated privileges with the guest.

  - CVE-2010-0307
    Mathias Krause reported an issue with the
    load_elf_binary code on the amd64 flavor kernels that
    allows local users to cause a denial of service (system
    crash).

  - CVE-2010-0309
    Marcelo Tosatti fixed an issue in the PIT emulation code
    in the KVM subsystem that allows privileged users in a
    guest domain to cause a denial of service (crash) of the
    host system.

  - CVE-2010-0410
    Sebastian Krahmer discovered an issue in the netlink
    connector subsystem that permits local users to allocate
    large amounts of system memory resulting in a denial of
    service (out of memory).

  - CVE-2010-0415
    Ramon de Carvalho Valle discovered an issue in the
    sys_move_pages interface, limited to amd64, ia64 and
    powerpc64 flavors in Debian. Local users can exploit
    this issue to cause a denial of service (system crash)
    or gain access to sensitive kernel memory."

"Upgrade the linux-2.6 and user-mode-linux packages.

For the stable distribution (lenny), this problem has been fixed in
version 2.6.26-21lenny3.

For the oldstable distribution (etch), these problems, where
applicable, will be fixed in updates to linux-2.6 and linux-2.6.24.

Note: Debian carefully tracks all known security issues across every
linux kernel package in all releases under active security support.
However, given the high frequency at which low-severity security
issues are discovered in the kernel and the resource requirements of
doing an update, updates for lower priority issues will normally not
be released for all kernels at the same time. Rather, they will be
released in a staggered or 'leap-frog' fashion.

The following matrix lists additional source packages that were
rebuilt for compatibility with or to take advantage of this update :

"USN-947-1 fixed vulnerabilities in the Linux kernel. Fixes for
CVE-2010-0419 caused failures when using KVM in certain situations.
This update reverts that fix until a better solution can be found.

We apologize for the inconvenience.

It was discovered that the Linux kernel did not correctly handle
memory protection of the Virtual Dynamic Shared Object page when
running a 32-bit application on a 64-bit kernel. A local attacker
could exploit this to cause a denial of service. (Only affected Ubuntu
6.06 LTS.) (CVE-2009-4271)

It was discovered that the r8169 network driver did not
correctly check the size of Ethernet frames. A remote
attacker could send specially crafted traffic to crash the
system, leading to a denial of service. (CVE-2009-4537)

Wei Yongjun discovered that SCTP did not correctly validate
certain chunks. A remote attacker could send specially
crafted traffic to monopolize CPU resources, leading to a
denial of service. (Only affected Ubuntu 6.06 LTS.)
(CVE-2010-0008)

It was discovered that KVM did not correctly limit certain
privileged IO accesses on x86. Processes in the guest OS
with access to IO regions could gain further privileges
within the guest OS. (Did not affect Ubuntu 6.06 LTS.)
(CVE-2010-0298, CVE-2010-0306, CVE-2010-0419)

Evgeniy Polyakov discovered that IPv6 did not correctly
handle certain TUN packets. A remote attacker could exploit
this to crash the system, leading to a denial of service.
(Only affected Ubuntu 8.04 LTS.) (CVE-2010-0437)

Sachin Prabhu discovered that GFS2 did not correctly handle
certain locks. A local attacker with write access to a GFS2
filesystem could exploit this to crash the system, leading
to a denial of service. (CVE-2010-0727)

Jamie Strandboge discovered that network virtio in KVM did
not correctly handle certain high-traffic conditions. A
remote attacker could exploit this by sending specially
crafted traffic to a guest OS, causing the guest to crash,
leading to a denial of service. (Only affected Ubuntu 8.04
LTS.) (CVE-2010-0741)

Marcus Meissner discovered that the USB subsystem did not
correctly handle certain error conditions. A local attacker
with access to a USB device could exploit this to read
recently used kernel memory, leading to a loss of privacy
and potentially root privilege escalation. (CVE-2010-1083)

Neil Brown discovered that the Bluetooth subsystem did not
correctly handle large amounts of traffic. A physically
proximate remote attacker could exploit this by sending
specially crafted traffic that would consume all available
system memory, leading to a denial of service. (Ubuntu 6.06
LTS and 10.04 LTS were not affected.) (CVE-2010-1084)

Jody Bruchon discovered that the sound driver for the
AMD780V did not correctly handle certain conditions. A local
attacker with access to this hardward could exploit the flaw
to cause a system crash, leading to a denial of service.
(CVE-2010-1085)

Ang Way Chuang discovered that the DVB driver did not
correctly handle certain MPEG2-TS frames. An attacker could
exploit this by delivering specially crafted frames to
monopolize CPU resources, leading to a denial of service.
(Ubuntu 10.04 LTS was not affected.) (CVE-2010-1086)

Trond Myklebust discovered that NFS did not correctly handle
truncation under certain conditions. A local attacker with
write access to an NFS share could exploit this to crash the
system, leading to a denial of service. (Ubuntu 10.04 LTS
was not affected.) (CVE-2010-1087)

Al Viro discovered that automount of NFS did not correctly
handle symlinks under certain conditions. A local attacker
could exploit this to crash the system, leading to a denial
of service. (Ubuntu 6.06 LTS and Ubuntu 10.04 LTS were not
affected.) (CVE-2010-1088)

Matt McCutchen discovered that ReiserFS did not correctly
protect xattr files in the .reiserfs_priv directory. A local
attacker could exploit this to gain root privileges or crash
the system, leading to a denial of service. (CVE-2010-1146)

Eugene Teo discovered that CIFS did not correctly validate
arguments when creating new files. A local attacker could
exploit this to crash the system, leading to a denial of
service, or possibly gain root privileges if mmap_min_addr
was not set. (CVE-2010-1148)

Catalin Marinas and Tetsuo Handa discovered that the TTY
layer did not correctly release process IDs. A local
attacker could exploit this to consume kernel resources,
leading to a denial of service. (CVE-2010-1162)

Neil Horman discovered that TIPC did not correctly check its
internal state. A local attacker could send specially
crafted packets via AF_TIPC that would cause the system to
crash, leading to a denial of service. (Ubuntu 6.06 LTS was
not affected.) (CVE-2010-1187)

Masayuki Nakagawa discovered that IPv6 did not correctly
handle certain settings when listening. If a socket were
listening with the IPV6_RECVPKTINFO flag, a remote attacker
could send specially crafted traffic that would cause the
system to crash, leading to a denial of service. (Only
Ubuntu 6.06 LTS was affected.) (CVE-2010-1188)

Oleg Nesterov discovered that the Out-Of-Memory handler did
not correctly handle certain arrangements of processes. A
local attacker could exploit this to crash the system,
leading to a denial of service. (CVE-2010-1488).

"Updated kvm packages that fix multiple security issues and several
bugs are now available for Red Hat Enterprise Linux 5.

This update has been rated as having important security impact by the
Red Hat Security Response Team.

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.

The x86 emulator implementation was missing a check for the Current
Privilege Level (CPL) and I/O Privilege Level (IOPL). A user in a
guest could leverage these flaws to cause a denial of service (guest
crash) or possibly escalate their privileges within that guest.
(CVE-2010-0298, CVE-2010-0306)

A flaw was found in the Programmable Interval Timer (PIT) emulation.
Access to the internal data structure pit_state, which represents the
data state of the emulated PIT, was not properly validated in the
pit_ioport_read() function. A privileged guest user could use this
flaw to crash the host. (CVE-2010-0309)

A flaw was found in the USB passthrough handling code. A specially
crafted USB packet sent from inside a guest could be used to trigger a
buffer overflow in the usb_host_handle_control() function, which runs
under the QEMU-KVM context on the host. A user in a guest could
leverage this flaw to cause a denial of service (guest hang or crash)
or possibly escalate their privileges within the host. (CVE-2010-0297)

This update also fixes the following bugs :

* pvclock MSR values were not preserved during remote migration,
causing time drift for guests. (BZ#537028)

* SMBIOS table 4 data is now generated for Windows guests. (BZ#545874)

* if the qemu-kvm '-net user' option was used, unattended Windows XP
installations did not receive an IP address after reboot. (BZ#546562)

* when being restored from migration, a race condition caused Windows
Server 2008 R2 guests to hang during shutdown. (BZ#546563)

* the kernel symbol checking on the kvm-kmod build process has a
safety check for ABI changes. (BZ#547293)

* on hosts without high-res timers, Windows Server 2003 guests
experienced significant time drift. (BZ#547625)

* in some situations, installing Windows Server 2008 R2 from an ISO
image resulted in a blue screen 'BAD_POOL_HEADER' stop error.
(BZ#548368)

* a bug in the grow_refcount_table() error handling caused infinite
recursion in some cases. This caused the qemu-kvm process to hang and
eventually crash. (BZ#552159)

* for Windows Server 2003 R2, Service Pack 2, 32-bit guests, an
'unhandled vm exit' error could occur during reboot on some systems.
(BZ#552518)

* for Windows guests, QEMU could attempt to stop a stopped audio
device, resulting in a 'snd_playback_stop: ASSERT
playback_channel->base.active failed' error. (BZ#552519)

* the Hypercall driver did not reset the device on power-down.
(BZ#552528)

* mechanisms have been added to make older savevm versions to be
emitted in some cases. (BZ#552529)

* an error in the Makefile prevented users from using the source RPM
to install KVM. (BZ#552530)

* guests became unresponsive and could use up to 100% CPU when running
certain benchmark tests with more than 7 guests running
simultaneously. (BZ#553249)

* QEMU could terminate randomly with virtio-net and SMP enabled.
(BZ#561022)

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."

    Gleb Natapov discovered issues in the KVM subsystem
    where missing permission checks (CPL/IOPL) permit a user
    in a guest system to denial of service a guest (system
    crash) or gain escalated privileges with the guest.

  - CVE-2010-0309
    Marcelo Tosatti fixed an issue in the PIT emulation code
    in the KVM subsystem that allows privileged users in a
    guest domain to cause a denial of service (crash) of the
    host system.

  - CVE-2010-0419
    Paolo Bonzini found a bug in KVM that can be used to
    bypass proper permission checking while loading segment

"Updated kvm packages that fix multiple security issues and several
bugs are now available for Red Hat Enterprise Linux 5.

This update has been rated as having important security impact by the
Red Hat Security Response Team.

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.

The x86 emulator implementation was missing a check for the Current
Privilege Level (CPL) and I/O Privilege Level (IOPL). A user in a
guest could leverage these flaws to cause a denial of service (guest
crash) or possibly escalate their privileges within that guest.
(CVE-2010-0298, CVE-2010-0306)

A flaw was found in the Programmable Interval Timer (PIT) emulation.
Access to the internal data structure pit_state, which represents the
data state of the emulated PIT, was not properly validated in the
pit_ioport_read() function. A privileged guest user could use this
flaw to crash the host. (CVE-2010-0309)

A flaw was found in the USB passthrough handling code. A specially
crafted USB packet sent from inside a guest could be used to trigger a
buffer overflow in the usb_host_handle_control() function, which runs
under the QEMU-KVM context on the host. A user in a guest could
leverage this flaw to cause a denial of service (guest hang or crash)
or possibly escalate their privileges within the host. (CVE-2010-0297)

This update also fixes the following bugs :

* pvclock MSR values were not preserved during remote migration,
causing time drift for guests. (BZ#537028)

* SMBIOS table 4 data is now generated for Windows guests. (BZ#545874)

* if the qemu-kvm '-net user' option was used, unattended Windows XP
installations did not receive an IP address after reboot. (BZ#546562)

* when being restored from migration, a race condition caused Windows
Server 2008 R2 guests to hang during shutdown. (BZ#546563)

* the kernel symbol checking on the kvm-kmod build process has a
safety check for ABI changes. (BZ#547293)

* on hosts without high-res timers, Windows Server 2003 guests
experienced significant time drift. (BZ#547625)

* in some situations, installing Windows Server 2008 R2 from an ISO
image resulted in a blue screen 'BAD_POOL_HEADER' stop error.
(BZ#548368)

* a bug in the grow_refcount_table() error handling caused infinite
recursion in some cases. This caused the qemu-kvm process to hang and
eventually crash. (BZ#552159)

* for Windows Server 2003 R2, Service Pack 2, 32-bit guests, an
'unhandled vm exit' error could occur during reboot on some systems.
(BZ#552518)

* for Windows guests, QEMU could attempt to stop a stopped audio
device, resulting in a 'snd_playback_stop: ASSERT
playback_channel->base.active failed' error. (BZ#552519)

* the Hypercall driver did not reset the device on power-down.
(BZ#552528)

* mechanisms have been added to make older savevm versions to be
emitted in some cases. (BZ#552529)

* an error in the Makefile prevented users from using the source RPM
to install KVM. (BZ#552530)

* guests became unresponsive and could use up to 100% CPU when running
certain benchmark tests with more than 7 guests running
simultaneously. (BZ#553249)

* QEMU could terminate randomly with virtio-net and SMP enabled.
(BZ#561022)

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."
