<p>
XLI and Xloadimage are X11 image manipulation utilities.
</p>
</background>
<description>
<p>
When XLI or Xloadimage process an image, they create a new image
object to contain the new image, copying the title from the old image
to the newly created image. Ariel Berkman reported that the 'zoom',
'reduce', and 'rotate' functions use a fixed length buffer to contain
the new title, which could be overwritten by the NIFF or XPM image
processors.
</p>
</description>
<impact type="normal">
<p>
A malicious user could craft a malicious XPM or NIFF file and
entice a user to view it using XLI, or manipulate it using Xloadimage,
potentially resulting in the execution of arbitrary code with the
permissions of the user running XLI or Xloadimage.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All XLI users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=media-gfx/xli-1.17.0-r2&quot;</code>
<p>
All Xloadimage users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=media-gfx/xloadimage-4.1-r4&quot;</code>
