Description

Remote exploitation of a buffer overflow vulnerability in the NTLM authentication helper routine of the Squid Web Proxy Cache could allow a remote attacker to execute arbitrary code. A remote attacker can compromise a target system if the Squid Proxy is configured to use the NTLM authentication helper. The attacker can send an overly long password to overflow the buffer and execute arbitrary code.
