"Updated kernel packages that fix various 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.

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

These updated packages fix the following security issues :

* on AMD64 architectures, the possibility of a kernel crash was
discovered by testing the Linux kernel process-trace ability. This
could allow a local unprivileged user to cause a denial of service
(kernel crash). (CVE-2008-1615, Important)

* on 64-bit architectures, the possibility of a timer-expiration value
overflow was found in the Linux kernel high-resolution timers
functionality, hrtimer. This could allow a local unprivileged user to
setup a large interval value, forcing the timer expiry value to become
negative, causing a denial of service (kernel hang). (CVE-2007-6712,
Important)

* the possibility of a kernel crash was found in the Linux kernel
IPsec protocol implementation, due to improper handling of fragmented
ESP packets. When an attacker controlling an intermediate router
fragmented these packets into very small pieces, it would cause a
kernel crash on the receiving node during packet reassembly.
(CVE-2007-6282, Important)

* a potential denial of service attack was discovered in the Linux
kernel PWC USB video driver. A local unprivileged user could use this
flaw to bring the kernel USB subsystem into the busy-waiting state,
causing a denial of service. (CVE-2007-5093, Low)

As well, these updated packages fix the following bugs :

* in certain situations, a kernel hang and a possible panic occurred
when disabling the cpufreq daemon. This may have prevented system
reboots from completing successfully.

* continual 'softlockup' messages, which occurred on the guest's
console after a successful save and restore of a Red Hat Enterprise
Linux 5 para-virtualized guest, have been resolved.

* in the previous kernel packages, the kernel may not have reclaimed
NFS locks after a system reboot.

Red Hat Enterprise Linux 5 users are advised to upgrade to these
updated packages, which contain backported patches to resolve these
issues."

"This kernel update fixes quite a number of security problems :

  - A remote attacker could crash the IPSec/IPv6 stack by
    sending a bad ESP packet. This requires the host to be
    able to receive such packets (default filtered by the
    firewall). (CVE-2007-6282)

  - A problem in SIT IPv6 tunnel handling could be used by
    remote attackers to immediately crash the machine.
    (CVE-2008-2136)

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

  - An information leakage during coredumping of root
    processes was fixed. (CVE-2007-6206)

  - 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 dnotify race condition, which could be used by
    local attackers to potentially execute code.
    (CVE-2008-1375)

  - A ptrace bug could be used by local attackers to hang
    their own processes indefinitely. (CVE-2007-5500)

  - Clear the 'direction' flag before calling signal
    handlers. For specific not yet identified programs under
    specific timing conditions this could potentially have
    caused memory corruption or code execution.
    (CVE-2008-1367)

  - The isdn_ioctl function in isdn_common.c allowed local
    users to cause a denial of service via a crafted ioctl
    struct in which ioctls is not null terminated, which
    triggers a buffer overflow. (CVE-2007-6151)

Non security related changes :

OCFS2 was updated to version v1.2.9-1-r3100.

Also a huge number of bugs were fixed. Please refer to the
RPM changelog for a detailed list."

"Updated kernel packages that fix various security issues and several
bugs are now available for Red Hat Enterprise Linux 4.

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

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

These updated packages fix the following security issues :

* the absence of a protection mechanism when attempting to access a
critical section of code has been found in the Linux kernel open file
descriptors control mechanism, fcntl. This could allow a local
unprivileged user to simultaneously execute code, which would
otherwise be protected against parallel execution. As well, a race
condition when handling locks in the Linux kernel fcntl functionality,
may have allowed a process belonging to a local unprivileged user to
gain re-ordered access to the descriptor table. (CVE-2008-1669,
Important)

* on AMD64 architectures, the possibility of a kernel crash was
discovered by testing the Linux kernel process-trace ability. This
could allow a local unprivileged user to cause a denial of service
(kernel crash). (CVE-2008-1615, Important)

* the absence of a protection mechanism when attempting to access a
critical section of code, as well as a race condition, have been found
in the Linux kernel file system event notifier, dnotify. This could
allow a local unprivileged user to get inconsistent data, or to send
arbitrary signals to arbitrary system processes. (CVE-2008-1375,
Important)

Red Hat would like to thank Nick Piggin for responsibly disclosing the
following issue :

* when accessing kernel memory locations, certain Linux kernel drivers
registering a fault handler did not perform required range checks. A
local unprivileged user could use this flaw to gain read or write
access to arbitrary kernel memory, or possibly cause a kernel crash.
(CVE-2008-0007, Important)

* the possibility of a kernel crash was found in the Linux kernel
IPsec protocol implementation, due to improper handling of fragmented
ESP packets. When an attacker controlling an intermediate router
fragmented these packets into very small pieces, it would cause a
kernel crash on the receiving node during packet reassembly.
(CVE-2007-6282, Important)

* a flaw in the MOXA serial driver could allow a local unprivileged
user to perform privileged operations, such as replacing firmware.
(CVE-2005-0504, Important)

As well, these updated packages fix the following bugs :

* multiple buffer overflows in the neofb driver have been resolved. It
was not possible for an unprivileged user to exploit these issues, and
as such, they have not been handled as security issues.

* a kernel panic, due to inconsistent detection of AGP aperture size,
has been resolved.

* a race condition in UNIX domain sockets may have caused 'recv()' to
return zero. In clustered configurations, this may have caused
unexpected failovers.

* to prevent link storms, network link carrier events were delayed by
up to one second, causing unnecessary packet loss. Now, link carrier
events are scheduled immediately.

* a client-side race on blocking locks caused large time delays on NFS
file systems.

* in certain situations, the libATA sata_nv driver may have sent
commands with duplicate tags, which were rejected by SATA devices.
This may have caused infinite reboots.

* running the 'service network restart' command may have caused
networking to fail.

* a bug in NFS caused cached information about directories to be
stored for too long, causing wrong attributes to be read.

* on systems with a large highmem/lowmem ratio, NFS write performance
may have been very slow when using small files.

* a bug, which caused network hangs when the system clock was wrapped
around zero, has been resolved.

Red Hat Enterprise Linux 4 users are advised to upgrade to these
updated packages, which contain backported patches to resolve these
issues."
