3. 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 remote management of virtualized

systems.

 

A flaw was found in the way libvirtd handled connection cleanup (when a

connection was being closed) under certain error conditions. A remote

attacker able to establish a read-only connection to libvirtd could use

this flaw to crash libvirtd or, potentially, execute arbitrary code with

the privileges of the root user. (CVE-2013-0170)

 

This issue was discovered by Tingting Zheng of Red Hat.

 

All users of libvirt are advised to upgrade to these updated packages,

which contain a backported patch to correct this issue. After installing

the updated packages, libvirtd will be restarted automatically.

 

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/knowledge/articles/11258
