"Updated kernel packages that resolve several security issues and fix
various 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.

[Updated 12th November 2008] The original packages distributed with
this errata had a bug which prevented the Xen kernel booting on older
hardware. We have updated the packages to correct this bug.

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

* the Xen implementation did not prevent applications running in a
para-virtualized guest from modifying CR4 TSC. This could cause a
local denial of service. (CVE-2007-5907, Important)

* Tavis Ormandy reported missing boundary checks in the Virtual
Dynamic Shared Objects (vDSO) implementation. This could allow a local
unprivileged user to cause a denial of service or escalate privileges.
(CVE-2008-3527, Important)

* the do_truncate() and generic_file_splice_write() functions did not
clear the setuid and setgid bits. This could allow a local
unprivileged user to obtain access to privileged information.
(CVE-2008-4210, CVE-2008-3833, Important)

* a flaw was found in the Linux kernel splice implementation. This
could cause a local denial of service when there is a certain failure
in the add_to_page_cache_lru() function. (CVE-2008-4302, Important)

* a flaw was found in the Linux kernel when running on AMD64 systems.
During a context switch, EFLAGS were being neither saved nor restored.
This could allow a local unprivileged user to cause a denial of
service. (CVE-2006-5755, Low)

* a flaw was found in the Linux kernel virtual memory implementation.
This could allow a local unprivileged user to cause a denial of
service. (CVE-2008-2372, Low)

* an integer overflow was discovered in the Linux kernel Datagram
Congestion Control Protocol (DCCP) implementation. This could allow a
remote attacker to cause a denial of service. By default, remote DCCP
is blocked by SELinux. (CVE-2008-3276, Low)

In addition, these updated packages fix the following bugs :

* random32() seeding has been improved.

* in a multi-core environment, a race between the QP async
event-handler and the destro_qp() function could occur. This led to
unpredictable results during invalid memory access, which could lead
to a kernel crash.

* a format string was omitted in the call to the request_module()
function.

* a stack overflow caused by an infinite recursion bug in the
binfmt_misc kernel module was corrected.

* the ata_scsi_rbuf_get() and ata_scsi_rbuf_put() functions now check
for scatterlist usage before calling kmap_atomic().

* a sentinel NUL byte was added to the device_write() function to
ensure that lspace.name is NUL-terminated.

* in the character device driver, a range_is_allowed() check was added
to the read_mem() and write_mem() functions. It was possible for an
illegitimate application to bypass these checks, and access /dev/mem
beyond the 1M limit by calling mmap_mem() instead. Also, the
parameters of range_is_allowed() were changed to cleanly handle
greater than 32-bits of physical address on 32-bit architectures.

* some of the newer Nehalem-based systems declare their CPU DSDT
entries as type 'Alias'. During boot, this caused an 'Error attaching
device data' message to be logged.

* the evtchn event channel device lacked locks and memory barriers.
This has led to xenstore becoming unresponsive on the Itanium(r)
architecture.

* sending of gratuitous ARP packets in the Xen frontend network driver
is now delayed until the backend signals that its carrier status has
been processed by the stack.

* on forcedeth devices, whenever setting ethtool parameters for link
speed, the device could stop receiving interrupts.

* the CIFS 'forcedirectio' option did not allow text to be appended to
files.

* the gettimeofday() function returned a backwards time on Intel(r) 64.

* residual-count corrections during UNDERRUN handling were added to
the qla2xxx driver.

* the fix for a small quirk was removed for certain Adaptec
controllers for which it caused problems.

* the 'xm trigger init' command caused a domain panic if a userland
application was running on a guest on the Intel(r) 64 architecture.

Users of kernel should upgrade to these updated packages, which
contain backported patches to correct these issues."

    being neither saved nor restored. This could allow a
    local unprivileged user to cause a denial of service.
    (CVE-2006-5755, Low)

  - a flaw was found in the Linux kernel virtual memory
    implementation. This could allow a local unprivileged
    user to cause a denial of service. (CVE-2008-2372, Low)

  - an integer overflow was discovered in the Linux kernel
    Datagram Congestion Control Protocol (DCCP)
    implementation. This could allow a remote attacker to
    cause a denial of service. By default, remote DCCP is
    blocked by SELinux. (CVE-2008-3276, Low)

In addition, these updated packages fix the following bugs :

  - random32() seeding has been improved.

  - in a multi-core environment, a race between the QP async
    event-handler and the destro_qp() function could occur.
    This led to unpredictable results during invalid memory
    access, which could lead to a kernel crash.

  - a format string was omitted in the call to the
    request_module() function.

  - a stack overflow caused by an infinite recursion bug in
    the binfmt_misc kernel module was corrected.

  - the ata_scsi_rbuf_get() and ata_scsi_rbuf_put()
    functions now check for scatterlist usage before calling
    kmap_atomic().

  - a sentinel NUL byte was added to the device_write()
    function to ensure that lspace.name is NUL-terminated.

  - in the character device driver, a range_is_allowed()
    check was added to the read_mem() and write_mem()
    functions. It was possible for an illegitimate
    application to bypass these checks, and access /dev/mem
    beyond the 1M limit by calling mmap_mem() instead. Also,
    the parameters of range_is_allowed() were changed to
    cleanly handle greater than 32-bits of physical address
    on 32-bit architectures.

  - some of the newer Nehalem-based systems declare their
    CPU DSDT entries as type 'Alias'. During boot, this
    caused an 'Error attaching device data' message to be
    logged.

  - the evtchn event channel device lacked locks and memory
    barriers. This has led to xenstore becoming unresponsive
    on the Itanium® architecture.

  - sending of gratuitous ARP packets in the Xen frontend
    network driver is now delayed until the backend signals
    that its carrier status has been processed by the stack.

  - on forcedeth devices, whenever setting ethtool
    parameters for link speed, the device could stop
    receiving interrupts.

  - the CIFS 'forcedirectio' option did not allow text to be
    appended to files.

  - the gettimeofday() function returned a backwards time on
    Intel® 64.

  - residual-count corrections during UNDERRUN handling were
    added to the qla2xxx driver.

  - the fix for a small quirk was removed for certain
    Adaptec controllers for which it caused problems.

  - the 'xm trigger init' command caused a domain panic if a
    userland application was running on a guest on the

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

[Updated 12th November 2008] The original packages distributed with
this errata had a bug which prevented the Xen kernel booting on older
hardware. We have updated the packages to correct this bug.

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

* the Xen implementation did not prevent applications running in a
para-virtualized guest from modifying CR4 TSC. This could cause a
local denial of service. (CVE-2007-5907, Important)

* Tavis Ormandy reported missing boundary checks in the Virtual

It was discovered that the disabling of the ZERO_PAGE optimization
could lead to large memory consumption. A local attacker could exploit
this to allocate all available memory, leading to a denial of service.
(CVE-2008-2372)

It was discovered that the Datagram Congestion Control Protocol (DCCP)
did not correctly validate its arguments. If DCCP was in use, a remote
attacker could send specially crafted network traffic and cause a
system crash, leading to a denial of service. (CVE-2008-3276)

It was discovered that the SBNI WAN driver did not correctly check for
the NET_ADMIN capability. A malicious local root user lacking
CAP_NET_ADMIN would be able to change the WAN device configuration,
leading to a denial of service. (CVE-2008-3525)

It was discovered that the Stream Control Transmission Protocol (SCTP)
did not correctly validate the key length in the SCTP_AUTH_KEY option.
If SCTP is in use, a remote attacker could send specially crafted
network traffic that would crash the system, leading to a denial of
service. (CVE-2008-3526)

It was discovered that the tmpfs implementation did not correctly

exploit this to crash the system, leading to a denial of service.
(CVE-2008-3534)

It was discovered that the readv/writev functions did not correctly
handle certain sequences of file operations. A local attacker could
exploit this to crash the system, leading to a denial of service.
(CVE-2008-3535)

It was discovered that SCTP did not correctly validate its userspace
arguments. A local attacker could call certain sctp_* functions with
malicious options and cause a system crash, leading to a denial of
service. (CVE-2008-3792, CVE-2008-4113, CVE-2008-4445)

It was discovered the the i915 video driver did not correctly validate
memory addresses. A local attacker could exploit this to remap memory
that could cause a system crash, leading to a denial of service.
(CVE-2008-3831)

Johann Dahm and David Richter discovered that NFSv4 did not correctly

"From Red Hat Security Advisory 2008:0957 :

Updated kernel packages that resolve several security issues and fix
various 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.

[Updated 12th November 2008] The original packages distributed with
this errata had a bug which prevented the Xen kernel booting on older
hardware. We have updated the packages to correct this bug.

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

* the Xen implementation did not prevent applications running in a
para-virtualized guest from modifying CR4 TSC. This could cause a
local denial of service. (CVE-2007-5907, Important)

* Tavis Ormandy reported missing boundary checks in the Virtual
Dynamic Shared Objects (vDSO) implementation. This could allow a local
unprivileged user to cause a denial of service or escalate privileges.
(CVE-2008-3527, Important)

* the do_truncate() and generic_file_splice_write() functions did not
clear the setuid and setgid bits. This could allow a local
unprivileged user to obtain access to privileged information.
(CVE-2008-4210, CVE-2008-3833, Important)

* a flaw was found in the Linux kernel splice implementation. This
could cause a local denial of service when there is a certain failure
in the add_to_page_cache_lru() function. (CVE-2008-4302, Important)

* a flaw was found in the Linux kernel when running on AMD64 systems.
During a context switch, EFLAGS were being neither saved nor restored.
This could allow a local unprivileged user to cause a denial of
service. (CVE-2006-5755, Low)

* a flaw was found in the Linux kernel virtual memory implementation.
This could allow a local unprivileged user to cause a denial of
service. (CVE-2008-2372, Low)

* an integer overflow was discovered in the Linux kernel Datagram
Congestion Control Protocol (DCCP) implementation. This could allow a
remote attacker to cause a denial of service. By default, remote DCCP
is blocked by SELinux. (CVE-2008-3276, Low)

In addition, these updated packages fix the following bugs :

* random32() seeding has been improved.

* in a multi-core environment, a race between the QP async
event-handler and the destro_qp() function could occur. This led to
unpredictable results during invalid memory access, which could lead
to a kernel crash.

* a format string was omitted in the call to the request_module()
function.

* a stack overflow caused by an infinite recursion bug in the
binfmt_misc kernel module was corrected.

* the ata_scsi_rbuf_get() and ata_scsi_rbuf_put() functions now check
for scatterlist usage before calling kmap_atomic().

* a sentinel NUL byte was added to the device_write() function to
ensure that lspace.name is NUL-terminated.

* in the character device driver, a range_is_allowed() check was added
to the read_mem() and write_mem() functions. It was possible for an
illegitimate application to bypass these checks, and access /dev/mem
beyond the 1M limit by calling mmap_mem() instead. Also, the
parameters of range_is_allowed() were changed to cleanly handle
greater than 32-bits of physical address on 32-bit architectures.

* some of the newer Nehalem-based systems declare their CPU DSDT
entries as type 'Alias'. During boot, this caused an 'Error attaching
device data' message to be logged.

* the evtchn event channel device lacked locks and memory barriers.
This has led to xenstore becoming unresponsive on the Itanium(r)
architecture.

* sending of gratuitous ARP packets in the Xen frontend network driver
is now delayed until the backend signals that its carrier status has
been processed by the stack.

* on forcedeth devices, whenever setting ethtool parameters for link
speed, the device could stop receiving interrupts.

* the CIFS 'forcedirectio' option did not allow text to be appended to
files.

* the gettimeofday() function returned a backwards time on Intel(r) 64.

* residual-count corrections during UNDERRUN handling were added to
the qla2xxx driver.

* the fix for a small quirk was removed for certain Adaptec
controllers for which it caused problems.

* the 'xm trigger init' command caused a domain panic if a userland
application was running on a guest on the Intel(r) 64 architecture.

Users of kernel should upgrade to these updated packages, which
contain backported patches to correct these issues."

"This is a respin of the previous kernel update, which got retracted
due to an IDE-CDROM regression, where any IDE CDROM access would hang
or crash the system. Only this problem was fixed additionally.

This kernel update fixes the following security problems :

  - On x86_64 a denial of service attack could be used by
    local attackers to immediately panic / crash the
    machine. (CVE-2008-1615)

  - Fixed a SMP ordering problem in fcntl_setlk could
    potentially allow local attackers to execute code by
    timing file locking. (CVE-2008-1669)

  - Fixed a resource starvation problem in the handling of
    ZERO mmap pages. (CVE-2008-2372)

  - The asn1 implementation in (a) the Linux kernel, as used
    in the cifs and ip_nat_snmp_basic modules does not
    properly validate length values during decoding of ASN.1
    BER data, which allows remote attackers to cause a
    denial of service (crash) or execute arbitrary code via
    (1) a length greater than the working buffer, which can
    lead to an unspecified overflow; (2) an oid length of
    zero, which can lead to an off-by-one error; or (3) an
    indefinite length for a primitive encoding.
    (CVE-2008-1673)

  - Various tty / serial devices did not check
    functionpointers for NULL before calling them, leading
    to potential crashes or code execution. The devices
    affected are usually only accessible by the root user
    though. (CVE-2008-2812)

  - A missing permission check in mount changing was added
    which could have been used by local attackers to change
    the mountdirectory. (CVE-2008-2931)

Additionally a very large number of bugs was fixed. Details can be
found in the RPM changelog of the included packages.

OCFS2 has been upgraded to the 1.4.1 release :

  - Endian fixes

  - Use slab caches for DLM objects

  - Export DLM state info to debugfs

  - Avoid ENOSPC in rare conditions when free inodes are
    reserved by other nodes

  - Error handling fix in ocfs2_start_walk_page_trans()

  - Cleanup lockres printing

  - Allow merging of extents

  - Fix to allow changing permissions of symlinks

  - Merged local fixes upstream (no code change)"
