<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 ">=media-libs/libexif-0.5.12-r1"</code>
