**Name of the Vulnerable Software and Affected Versions** Squid versions prior to 2.6.STABLE7 **Description** The issue allows remote attackers to cause a denial of service, potentially leading to a disruption in the availability of protected information. This can be achieved by overloading the external acl queue, which triggers an infinite loop in the `aclMatchExternal` function. The exploitation of this issue can be done remotely. **Recommendations** For Squid versions prior to 2.6.STABLE7, update to version 2.6.STABLE7 or later to resolve the issue. As a temporary workaround, consider restricting access to the `aclMatchExternal` function to minimize the risk of exploitation.
