Type/Severity

Security Advisory: Moderate

Topic

Updated libvirt packages that fix one security issue are now available for
Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having moderate
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 libvirt library is a C API for managing and interacting with the
virtualization capabilities of Linux and other operating systems. In
addition, libvirt provides tools for remotely managing virtualized systems.

A flaw was found in the way libvirtd handled error reporting for concurrent
connections. A remote attacker able to establish read-only connections to
libvirtd on a server could use this flaw to crash libvirtd. (CVE-2011-1486)

All libvirt users are advised to upgrade to these updated packages, which
contain backported patches to resolve this issue. After installing the
updated packages, libvirtd must be restarted ("service libvirtd restart")
for this update to take effect.

Solution

Before applying this update, make sure all previously-released errata
