CVE-2007-0248  (opens in a new tab)

How to fix?

Upgrade Echo:latest squid to version 2.6.5-4 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream squid package and not the squid package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

The aclMatchExternal function in Squid before 2.6.STABLE7 allows remote attackers to cause a denial of service (crash) by causing an external_acl queue overload, which triggers an infinite loop.
