  <title>OpenMotif, LessTif: New libXpm buffer overflows</title>
  <synopsis>
    A new vulnerability has been discovered in libXpm, which is included in
    OpenMotif and LessTif, that can potentially lead to remote code execution.
  </synopsis>

    <p>
    LessTif is a clone of OSF/Motif, which is a standard user
    interface toolkit available on Unix and Linux. OpenMotif also provides
    a free version of the Motif toolkit for open source applications.

    <p>
    Chris Gilbert discovered potentially exploitable buffer overflow
    cases in libXpm that weren't fixed in previous libXpm security
    advisories.
    </p>
  </description>
  <impact type="normal">
    <p>
    A carefully-crafted XPM file could crash applications making use
    of the OpenMotif or LessTif toolkits, 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 OpenMotif users should upgrade to an unaffected version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose x11-libs/openmotif</code>
    <p>
    All LessTif users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=x11-libs/lesstif-0.94.0-r2&quot;</code>
  </resolution>
