  <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.
