  <title>teTeX, pTeX, CSTeX: Multiple overflows in included XPdf code</title>
  <synopsis>
    CSTeTeX, pTeX, and teTeX include vulnerable XPdf code to handle PDF files,
    making them vulnerable to the execution of arbitrary code.

    teTex is a complete TeX distribution. It is used for creating and
    manipulating LaTeX documents. CSTeX is a TeX distribution with Czech
    and Slovak support. pTeX is and ASCII publishing TeX distribution.

  <description>
    <p>
    CSTeX, teTex, and pTeX include XPdf code to handle PDF files. This
    XPdf code is vulnerable to several heap overflows (GLSA 200512-08) as
    well as several buffer and integer overflows discovered by Chris Evans
    (CESA-2005-003).
    </p>
  </description>
  <impact type="normal">
    <p>
    An attacker could entice a user to open a specially crafted PDF
    file with teTeX, pTeX or CSTeX, potentially resulting in the execution
    of arbitrary code with the rights of the user running the affected
    application.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All teTex users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=app-text/tetex-2.0.2-r8&quot;</code>
    <p>
    All CSTeX users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=app-text/cstetex-2.0.2-r2&quot;</code>
    <p>
    All pTeX users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=app-text/ptex-3.1.5-r1&quot;</code>
