Victor Stinner reported an integer overflow in the
|
|
exif_data_load_data_entry() function from file exif-data.c while
|
|
handling Exif data.

<impact type="normal">
|
|
<p>
|
|
An attacker could entice a user to process a file with specially
|
|
crafted Exif extensions with an application making use of libexif,
|
|
which will trigger the integer overflow and potentially execute
|
|
arbitrary code or crash 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. Please note
|
|
that users upgrading from "<=media-libs/libexif-0.6.13" should also run
|
|
revdep-rebuild after their upgrade.
|
|
</p>

<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=media-libs/libexif-0.6.15"
|
|
# revdep-rebuild --library=/usr/lib/libexif.so</code>
