Description Jan Lieskovsky 2013-07-15 11:16:12 EDT
A denial of service flaw was found in the way Squid, the proxy caching server, used to process port specific information, present in the HTTP Host: header of certain HTTP requests. A remote attacker could provide a specially-crafted HTTP request that, when processed would lead to Squid daemon termination (denial of service).
