Synopsis
========

Multiple vulnerabilities have been found in libTIFF, the worst of which
may allow 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              < 4.0.7                    >= 4.0.7

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

Multiple vulnerabilities have been discovered in libTIFF. Please review
the CVE identifier and bug reports referenced for details.

Impact
======

A remote attacker could entice a user to process a specially crafted
image file, possibly resulting in execution of arbitrary code with the
privileges of the process or 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-4.0.7"
