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.
