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


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


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


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.


There is no known workaround at this time.


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.
