Synopsis:          Moderate: kernel security and bug fix update
Advisory ID:       RHSA-2010:0839-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2010-0839.html
Issue date:        2010-11-09

=====================================================================

1. Summary:

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

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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux (v. 5 server) - i386, ia64, noarch, ppc, s390x, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, noarch, x86_64

3. Description:

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

This update fixes the following security issues:

* A NULL pointer dereference flaw was found in the io_submit_one() function
in the Linux kernel asynchronous I/O implementation. A local, unprivileged
user could use this flaw to cause a denial of service. (CVE-2010-3066,
Moderate)

* A flaw was found in the xfs_ioc_fsgetxattr() function in the Linux kernel
XFS file system implementation. A data structure in xfs_ioc_fsgetxattr()
was not initialized properly before being copied to user-space. A local,
unprivileged user could use this flaw to cause an information leak.
(CVE-2010-3078, Moderate)

* The exception fixup code for the __futex_atomic_op1, __futex_atomic_op2,
and futex_atomic_cmpxchg_inatomic() macros replaced the LOCK prefix with a
NOP instruction. A local, unprivileged user could use this flaw to cause a
denial of service. (CVE-2010-3086, Moderate)

* A flaw was found in the tcf_act_police_dump() function in the Linux
kernel network traffic policing implementation. A data structure in
tcf_act_police_dump() was not initialized properly before being copied to
user-space. A local, unprivileged user could use this flaw to cause an
information leak. (CVE-2010-3477, Moderate)

* A missing upper bound integer check was found in the sys_io_submit()
function in the Linux kernel asynchronous I/O implementation. A local,
unprivileged user could use this flaw to cause an information leak.
(CVE-2010-3067, Low)

Red Hat would like to thank Tavis Ormandy for reporting CVE-2010-3066,
CVE-2010-3086, and CVE-2010-3067, and Dan Rosenberg for reporting
CVE-2010-3078.

This update also fixes several bugs. Documentation for these bug fixes will
be available shortly from the Technical Notes document linked to in the
References section.

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.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
http://kbase.redhat.com/faq/docs/DOC-11259

To install kernel packages manually, use "rpm -ivh [package]". Do not
use "rpm -Uvh" as that will remove the running kernel binaries from
your system. You may use "rpm -e" to remove old kernels after
determining that the new kernel functions properly on your system.
