Synopsis
========

An integer overflow has been found in the TIFF library image decoding
routines and the tiffdump utility, potentially allowing arbitrary code
execution.

Background
==========

The TIFF library contains encoding and decoding routines for the Tag
Image File Format. It is called by numerous programs, including GNOME
and KDE applications, to interpret TIFF images.

Affected packages
=================

    -------------------------------------------------------------------
     Package          /  Vulnerable  /                      Unaffected
    -------------------------------------------------------------------
  1  media-libs/tiff     < 3.7.1-r1                        >= 3.7.1-r1

Description
===========

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.

Resolution
==========

All TIFF library users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-libs/tiff-3.7.1-r1"
