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 "cache update reply processing" functionality in Squid 2.x before 2.6.STABLE17 and Squid 3.0 allows remote attackers to cause a denial of service (crash) via unknown vectors related to HTTP headers and an Array memory leak during requests for cached objects.
