    <package name="app-office/texmacs" auto="yes" arch="*">
      <unaffected range="ge">1.0.7.2-r1</unaffected>

    <p>GNU TeXmacs is a free WYSIWYG editing platform with special features for
      scientists.
    </p>
  </background>
  <description>
    <p>The texmacs and tm_mupad_help scripts in TeXmacs place a zero-length
      directory name in the LD_LIBRARY_PATH, which might result in the current
      working directory (.) to be included when searching for dynamically
      linked libraries.
    </p>
  </description>
  <impact type="high">
    <p>A local attacker could gain escalated privileges via a specially crafted
      shared library.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All GNU TeXmacs users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=app-office/texmacs-1.0.7.2-r1"
    </code>
    
    <p>NOTE: This is a legacy GLSA. Updates for all affected architectures are
      available since April 02, 2011. It is likely that your system is already
      no longer affected by this issue.
