<p>
libexif is a library for parsing, editing and saving EXIF data.
</p>
</background>
<description>
<p>
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.
</p>
</description>
<impact type="normal">
<p>
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.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All libexif users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=media-libs/libexif-0.5.12-r1&quot;</code>
</resolution>
