Date: January 19, 2014
Bug(s): #426366
ID: 201401-10
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: media-libs/libexif
Vulnerable: < 0.6.21

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