libexif is a library for parsing, editing and saving Exif metadata from
|
|
images. Exif, the Exchangeable image file format, specifies the
|
|
addition of metadata tags to JPEG, TIFF and RIFF files.

|
|
Meder Kydyraliev (Google Security) discovered an integer overflow
|
|
vulnerability in the exif_data_load_data_thumbnail() function leading
|
|
to a memory corruption (CVE-2007-6352) and an infinite recursion in the
|
|
exif_loader_write() function (CVE-2007-6351).

|
<impact type="normal">
|
|
<p>
|
|
An attacker could entice the user of an application making use of
|
|
libexif to load an image file with specially crafted Exif tags,
|
|
possibly resulting in the execution of arbitrary code with the
|
|
privileges of the user running the application or a Denial of Service.
|
|
</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-0.6.16-r1"</code>
