Description Pedro Sampaio 2019-11-08 19:42:29 UTC
Due to incorrect message parsing Squid is vulnerable to an HTTP request splitting issue. This issue allows attackers to smuggle HTTP requests through frontend software to a Squid which splits the HTTP Request pipeline differently. The resulting Response messages corrupt caches between client and Squid with attacker controlled content at arbitrary URLs.
