Multiple memory leaks in tools/cachemgr.cc in cachemgr.cgi in Squid
2.x and 3.x before 3.1.22, 3.2.x before 3.2.4, and 3.3.x before
3.3.0.2 allow remote attackers to cause a denial of service (memory
consumption) via (1) invalid Content-Length headers, (2) long POST
requests, or (3) crafted authentication credentials (CVE-2012-5643).

cachemgr.cgi in Squid 3.1.x and 3.2.x, possibly 3.1.22, 3.2.4, and
other versions, allows remote attackers to cause a denial of service
(resource consumption) via a crafted request. NOTE: this issue is due
to an incorrect fix for CVE-2012-5643, possibly involving an incorrect
order of arguments or incorrect comparison (CVE-2013-0189).

The updated packages have been patched to correct these issues."
