==========================================================================

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

- Ubuntu 12.04 LTS

Summary:

libproxy could be made to crash or run programs if it received specially
crafted network traffic.

Software Description:
- libproxy: automatic proxy configuration management library

Details:

Tomas Mraz discovered that libproxy incorrectly handled certain PAC files.
A remote attacker could use this issue to cause libproxy to crash, or to
possibly execute arbitrary code. (CVE-2012-4504, CVE-2012-4505)

Update instructions:

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

Ubuntu 12.04 LTS:
