Description Agostino Sarubbo gentoo-dev 2013-07-15 18:39:47 UTC
From ${URL} :

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).
