Synopsis
========

Multiple vulnerabilities have been found in LibTIFF, the worst of which
could result in the execution of arbitrary code.

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              < 4.2.0                    >= 4.2.0

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

Multiple vulnerabilities have been discovered in LibTIFF. Please review
the referenced CVE identifiers for details.

Impact
======

A remote attacker, by enticing the user to process a specially crafted
TIFF file, could possibly execute arbitrary code with the privileges of
the process, or cause a Denial of Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All LibTIFF users should upgrade to the latest version:

   # emerge --sync
   # emerge --ask --oneshot --verbose ">=media-libs/tiff-4.2.0"
