Descriptions

HAProxy 2.2 through 3.1.6, in certain uncommon configurations, has a sample_conv_regsub heap-based buffer overflow because of mishandling of the replacement of multiple short patterns with a longer one.

USN-7431-1 fixed a vulnerability in HAProxy. This update provides the corresponding update for Ubuntu 25.04. 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.
