  <description>
    <p>
    Chris Evans has discovered various integer and stack overflows in libXpm,
    which is shipped as a part of the X Window System. LessTif, an application
    that includes this library, is susceptible to the same issues.
    </p>
  </description>
  <impact type="normal">
    <p>
    A carefully-crafted XPM file could crash applications that are linked
    against libXpm, such as LessTif, potentially allowing the execution of
    arbitrary code with the privileges of the user running the application.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All LessTif users should upgrade to the latest version:
    </p>
    <code>
    # emerge sync

    # emerge -pv ">=x11-libs/lesstif-0.93.97"
    # emerge ">=x11-libs/lesstif-0.93.97"</code>
  </resolution>
