NVD description
HAProxy 3 before 3.4.6 allows a remote unauthenticated attacker to cause a denial of service (persistent worker-thread CPU exhaustion) via an HTTP/1.1 chunked request. Although the H1 multiplexer drains the request before closing the stream, the parser repeatedly re-processes the same bytes without making progress. The affected thread stays busy at 100% CPU after timeouts expire and after the client disconnects, and repeated requests can consume all worker threads until the process is restarted.

Attention a la mise a jour de HAProxy 2.4.30-0ubuntu0.22.04.3 Pour corriger CVE-2026-110354 et CVE-2026-110353, ubuntu a backport le patch en 2.4 Mais ca pose de nombreux soucis sur des fichiers un peu plus gros que 24ko avec des troncatures et erreurs 502
