Red Hat Security Advisory

Synopsis: Important: Red Hat Enterprise Linux 5.7 kernel security and bug fix update
Advisory ID: RHSA-2011:1065-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2011-1065.html
Issue date: 2011-07-21
CVE Names: CVE-2011-1780 CVE-2011-2525 CVE-2011-2689
================================================== ===================

1. Summary:

Updated kernel packages that fix multiple security issues, address several
hundred bugs, and add numerous enhancements are now available as part of
the ongoing support and maintenance of Red Hat Enterprise Linux version 5.
This is the seventh regular update.

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.

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 flaw was found in the way the Xen hypervisor implementation handled
instruction emulation during virtual machine exits. A malicious user-space
process running in an SMP guest could trick the emulator into reading a
different instruction than the one that caused the virtual machine to exit.
An unprivileged guest user could trigger this flaw to crash the host. This
only affects systems with both an AMD x86 processor and the AMD
Virtualization (AMD-V) extensions enabled. (CVE-2011-1780, Important)

* A flaw allowed the tc_fill_qdisc() function in the Linux kernel's packet
scheduler API implementation to be called on built-in qdisc structures. A
local, unprivileged user could use this flaw to trigger a NULL pointer
dereference, resulting in a denial of service. (CVE-2011-2525, Moderate)

* A flaw was found in the way space was allocated in the Linux kernel's
Global File System 2 (GFS2) implementation. If the file system was almost
full, and a local, unprivileged user made an fallocate() request, it could
result in a denial of service. Note: Setting quotas to prevent users from
using all available disk space would prevent exploitation of this flaw.
(CVE-2011-2689, Moderate)

These updated kernel packages include a number of bug fixes and
enhancements. Space precludes documenting all of these changes in this
advisory. Refer to the Red Hat Enterprise Linux 5.7 Technical Notes for
information about the most significant bug fixes and enhancements included
in this update:

https://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5/html/5.7_Tech
nical_Notes/kernel.html#RHSA-2011-1065

All Red Hat Enterprise Linux 5 users are advised to install these updated
packages, which 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
https://access.redhat.com/kb/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.
