Synopsis
========

Multiple vulnerabilities have been found in libexif and exif, some of
which may allow execution of arbitrary code.

Background
==========

libexif is a library for parsing, editing and saving Exif metadata from
images. exif is a small command line interface for libexif.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  media-libs/libexif           < 0.6.21                  >= 0.6.21
  2  media-gfx/exif               < 0.6.21                  >= 0.6.21
    -------------------------------------------------------------------
     2 affected packages

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

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

Impact
======

A remote attacker could entice a user to open a specially crafted image
file using exif or an application linked against libexif, 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 libexif users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=media-libs/libexif-0.6.21"

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

All exif users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=media-gfx/exif-0.6.21"
