The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0718 to this issue. A bug was found in the way Squid handles access to the cachemgr.cgi script. It is possible for an authorised remote user to bypass access control lists with this flaw.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-1519 to this issue. Additionally, this update fixes the following bugs: - squid fails in the unpacking of squid-2.4.STABLE7-1.21as.5.src.rpm Users of Squid should upgrade to this updated package, which contains backported patches to correct these issues.
