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"
