low Nessus Plugin ID 53643

Language:

Synopsis

The remote CentOS host is missing one or more security updates.

Description

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.

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

Update the affected libvirt and / or libvirt.test packages.
