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

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

- Ubuntu 24.10
- Ubuntu 24.04 LTS
- Ubuntu 22.04 LTS

Summary:

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

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

Details:

Aleandro Prudenzano and Edoardo Geraci discovered that HAProxy incorrectly
handled certain uncommon configurations that replace multiple short
patterns with a longer one. A remote attacker could use this issue to cause
HAProxy to crash, resulting in a denial of service, or possibly execute
arbitrary code.

Update instructions:

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

Ubuntu 24.10
  haproxy                         2.9.10-1ubuntu1.2

Ubuntu 22.04 LTS
  haproxy                         2.4.24-0ubuntu0.22.04.2
