This script is Copyright (C) 2007-2015 Tenable Network Security, Inc.

Synopsis :

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

Description :

The remote host is affected by the vulnerability described in GLSA-200701-22
(Squid: Multiple Denial of Service vulnerabilities)

Squid fails to correctly handle ftp:// URI's. There is also an error in
the external_acl queue which can cause an infinite looping condition.

Impact :

An attacker could attempt to retrieve a specially crafted URI via a
Squid server causing the service to crash. If an attacker could
generate a sufficiently high load on the Squid services, they could
cause a Denial of Service by forcing Squid into an infinite loop.

Workaround :

There is no known workaround at this time.
