This script is Copyright (C) 2005-2014 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-200501-06
(tiff: New overflows in image decoding)

infamous41md found a potential integer overflow in the directory
entry count routines of the TIFF library (CAN-2004-1308). Dmitry V.
Levin found another similar issue in the tiffdump utility
(CAN-2004-1183).

Impact :

A remote attacker could entice a user to view a carefully crafted
TIFF image file, which would potentially lead to execution of arbitrary
code with the rights of the user viewing the image. This affects any
program that makes use of the TIFF library, including many web browsers
or mail readers.

Workaround :

There is no known workaround at this time.
