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.
