Debian Linux Security Advisory 5637-1 - Several security vulnerabilities have been discovered in Squid, a full featured web proxy cache. Due to programming errors in Squid's HTTP request parsing, remote attackers may be able to execute a denial of service attack by sending large X-Forwarded-For header or trigger a stack buffer overflow while performing HTTP Digest authentication. Other issues facilitate request smuggling past a firewall or a denial of service against Squid's Helper process management.
