haproxy vulnerability
==========================================================================

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

- Ubuntu 13.04
- Ubuntu 12.10
- Ubuntu 12.04 LTS

Summary:

HAProxy could be made to crash if it received specially crafted network
traffic.

Software Description:
- haproxy: fast and reliable load balancing reverse proxy

Details:

David Torgerson discovered that HAProxy incorrectly parsed certain HTTP
headers. A remote attacker could use this issue to cause HAProxy to stop
responding, resulting in a denial of service.

Update instructions:

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

Ubuntu 13.04:
  haproxy                         1.4.18-0ubuntu3.1

Ubuntu 12.10:
  haproxy                         1.4.18-0ubuntu2.2

Ubuntu 12.04 LTS:
  haproxy                         1.4.18-0ubuntu1.2

In general, a standard system update will make all the necessary changes.
