The RedHat squid program installs cachemgr.cgi in a public web directory, allowing remote attackers to use it as an intermediary to connect to other systems. This patch adds access controls to the cachemgr.cgi script, preventing it from being abused to reach other servers than allowed in a local configuration file. http://www.squid-cache.org/Versions/v2/2.5/bugs/#squid-2.5.STABLE9-cachemgr_conf
