5th June, 2013
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 13.04
- Ubuntu 12.10
- Ubuntu 12.04 LTS
Several security issues were fixed in libxres.
- libxres - X11 Resource extension library
Ilja van Sprundel discovered multiple security issues in various X.org
libraries and components. An attacker could use these issues to cause
applications to crash, resulting in a denial of service, or possibly
execute arbitrary code.
