Synopsis
========

Multiple vulnerabilities have been found in libTIFF, allowing remote
attackers to execute arbitrary code or cause Denial of Service.

Background
==========

libTIFF provides support for reading and manipulating TIFF (Tagged
Image File Format) images.

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-libs/tiff < 4.0.3-r6 *>= 3.9.7-r1
>= 4.0.3-r6

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

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

Impact
======

A remote attacker could entice a user to open a specially crafted TIFF
file with an application making use of libTIFF, possibly resulting in
execution of arbitrary code with the privileges of the user running the
application or a Denial of Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All libTIFF 4.* users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/tiff-4.0.3-r6"

All libTIFF 3.* users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/tiff-3.9.7-r1"

Packages which depend on this library may need to be recompiled. Tools
such as revdep-rebuild may assist in identifying these packages.
