This script is Copyright (C) 2009-2014 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-200907-16
(Python: Integer overflows)

Chris Evans reported multiple integer overflows in the expandtabs
method, as implemented by (1) the string_expandtabs function in
Objects/stringobject.c and (2) the unicode_expandtabs function in
Objects/unicodeobject.c.

Impact :

A remote attacker could exploit these vulnerabilities in Python
applications or daemons that pass user-controlled input to vulnerable
functions. The security impact is currently unknown but may include the
execution of arbitrary code or a Denial of Service.

Workaround :

There is no known workaround at this time.
