Problem 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. (CAN-2005-0194) Race condition in Squid 2.5.STABLE7 to 2.5.STABLE9, when using the Netscape Set-Cookie recommendations for handling cookies in caches, may cause Set-Cookie headers to be sent to other users, which allows attackers to steal the related cookies. (CAN-2005-0626) Squid 2.5.STABLE7 and earlier allows remote attackers to cause a denial of service (segmentation fault) by aborting the connection during a (1) PUT or (2) POST request, which causes Squid to access previosuly freed memory. (CAN-2005-0718) A bug in the way Squid processes errors in the access control list was also found. It is possible that an error in the access control list could give users more access than intended. (CAN-2005-1345) In addition, due to subtle bugs in the previous backported updates of squid (Bugzilla #14209), all the squid-2.5 versions have been updated to squid-2.5.STABLE9 with all the STABLE9 patches from the squid developers. The updated packages are patched to fix these problems.
