CVE-2005-0194 Information

Description

Squid 2.5 when processing the configuration file parses empty Access Control Lists (ACLs) including proxy_auth ACLs without defined auth schemes in a way that effectively removes arguments which could allow remote attackers to bypass intended ACLs if the administrator ignores the parser warnings.
