This script is Copyright (C) 2007-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200703-27
(Squid: Denial of Service)

Squid incorrectly handles TRACE requests that contain a 'Max-Forwards'
header field with value '0' in the clientProcessRequest() function.

Impact :

A remote attacker can send specially crafted TRACE HTTP requests that
will terminate the child process. A quickly repeated attack will lead
to a Denial of Service.

Workaround :

There is no known workaround at this time.
