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-200406-13
(Squid: NTLM authentication helper buffer overflow)

Squid is a full-featured Web Proxy Cache designed to run on Unix systems.
It supports proxying and caching of HTTP, FTP, and other URLs, as well as
SSL support, cache hierarchies, transparent caching, access control lists
and many other features.

Impact :

If Squid is configured to use NTLM authentication, an attacker could
exploit this vulnerability by sending a very long password. This could lead
to arbitrary code execution with the permissions of the user running Squid.

Workaround :

There is no known workaround at this time. All users are encouraged to
upgrade to the latest available version.
