<impact type="normal">
<p>A remote attacker could entice a user to open a specially crafted JPEG
file in an application linked against libjpeg-turbo, possibly resulting
in the remote execution of arbitrary code with the permissions of the
user running the application, or Denial of Service.
</p>
</impact>
<workaround>
<p>There is no known workaround at this time.</p>
</workaround>
<resolution>
<p>All libjpeg-turbo users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=media-libs/libjpeg-turbo-1.2.1"
</code>
<p>Packages which depend on this library may need to be recompiled. Tools
such as revdep-rebuild may assist in identifying some of these packages.
