Synopsis
=======
libexif fails to validate certain inputs, making it vulnerable to
buffer overflows.

Background
=========
libexif is a library for parsing, editing and saving EXIF data.

Affected packages
================
    -------------------------------------------------------------------
     Package             /   Vulnerable   /                 Unaffected
    -------------------------------------------------------------------
  1  media-libs/libexif      < 0.5.12-r1                  >= 0.5.12-r1

Description
==========
libexif contains a buffer overflow vulnerability in the EXIF tag
validation code. When opening an image with a specially crafted EXIF
tag, the lack of validation can cause applications linked to libexif to
crash.

Impact
=====
A specially crafted EXIF file could crash applications making use of
libexif, potentially allowing the execution of arbitrary code with the
privileges of the user running the application.

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-0.5.12-r1"
