libxml2 vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 13.04

Summary:

libxml2 could be made to crash or run programs if it opened a specially
crafted file.

Software Description:
- libxml2: GNOME XML library

Details:

It was discovered that libxml2 incorrectly handled memory management when
parsing certain XML files. An attacker could use this flaw to cause libxml2
to crash, resulting in a denial of service, or to possibly execute
arbitrary code.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:
