View affected systems

Topic

Updated xen packages that fix several security issues are now available for
Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having
important security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from the
CVE link in the References section.

Description

The xen packages contain administration tools and the xend service for
managing the kernel-xen kernel for virtualization on Red Hat Enterprise
Linux.

It was found that the xc_try_bzip2_decode() and xc_try_lzma_decode() decode
routines did not correctly check for a possible buffer size overflow in the
decoding loop. As well, several integer overflow flaws and missing
error/range checking were found that could lead to an infinite loop. A
privileged guest user could use these flaws to crash the guest or,
possibly, execute arbitrary code in the privileged management domain
(Dom0). (CVE-2011-1583)

All xen users are advised to upgrade to these updated packages, which
contain backported patches to correct these issues. The system must be
rebooted for this update to take effect.

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
