Fedora 13 : mingw32-libtiff-3.9.5-1.fc13 (2011-5955)

This script is Copyright (C) 2011-2015 Tenable Network Security, Inc.

Synopsis :

The remote Fedora host is missing a security update.

Description :

Update MinGW Windows cross-compiled libtiff to 3.9.5, incorporating
most of our previous patches.

Includes a fix for CVE-2011-1167: A flaw was reported in libtiff's
thunder decoder. The thunder decoder assumes 4bits per pixel, but if a
file has bitpersample set to a smaller value, or defaulted (1) then
the allocated strip buffer will be too small, and a heap-based buffer
overlow may occur. This could be used to crash an application linked
to libtiff, or execute arbitrary code with the privileges of the
application opening a malicious TIFF file.

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
