Fixed In Version: haproxy 2.5.2
Doc Type: If docs needed, set a value
Doc Text:
A flaw was found in the way HAProxy processed HTTP responses containing the "Set-Cookie2" header. This flaw could allow an attacker to send crafted HTTP response packets which lead to an infinite loop, eventually resulting in a denial of service condition. The highest threat from this vulnerability is availability.

Description Pedro Sampaio 2022-02-11 17:35:36 UTC 
A flaw was found in haproxy. Anybody who can add a "set-cookie2 X=Y" header into the return path from their server/backend will kill haproxy in 2.2 (and onwards), resulting in a denial of service.
