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	Architecture(s)
media-libs/tiff	< 4.0.3-r6	>= 4.0.3-r6	All supported architectures

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-r1:3"

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