Squid3, a fully featured Web proxy cache, is prone to a denial of service attack due to memory consumption caused by memory leaks in cachemgr.cgi :
CVE-2012-5643 squidโs cachemgr.cgi was vulnerable to excessive resource use. A remote attacker could exploit this flaw to perform a denial of service attack on the server and other hosted services.
CVE-2013-0189 The original patch for CVE-2012-5643 was incomplete. A remote attacker still could exploit this flaw to perform a denial of service attack.
