images.

<p>
|
|
iDefense Labs have discovered that the exif_data_load_data_entry()
|
|
function in libexif/exif-data.c improperly handles integer data while
|
|
working with an image with many EXIF components, allowing an integer
|
|
overflow possibly leading to a heap-based buffer overflow.
|
|

<impact type="normal">
|
|
<p>
|
|
An attacker could entice a user of an application making use of a
|
|
vulnerable version of libexif to load a specially crafted image file,
|
|
possibly resulting in a crash of the application or the execution of
|
|
arbitrary code with the rights 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-0.6.16"</code>
