Originally, Common Vulnerabilities and Exposures assigned an identifier CVE-2012-5643 (bug #887962) to the following vulnerability:
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.
Later it was found the upstream patch for CVE-2012-5643 issue to be incomplete, resulting in new patchset: [1] http://bazaar.launchpad.net/~squid/squid/3.2/revision/11743 [2] http://bazaar.launchpad.net/~squid/squid/3.2/revision/11744
