    Joachim Schrod discovered several buffer overflow vulnerabilities and
    an insecure temporary file creation in the "dvilj" application that is
    used by dvips to convert DVI files to printer formats (CVE-2007-5937,
    CVE-2007-5936). Bastien Roucaries reported that the "dvips" application
    is vulnerable to two stack-based buffer overflows when processing DVI
    documents with long \href{} URIs (CVE-2007-5935). teTeX also includes
    code from Xpdf that is vulnerable to a memory corruption and two
    heap-based buffer overflows (GLSA 200711-22); and it contains code from
    T1Lib that is vulnerable to a buffer overflow when processing an overly
    long font filename (GLSA 200710-12).

  <impact type="normal">
    <p>
    A remote attacker could entice a user to process a specially crafted
    DVI or PDF file which could lead to the execution of arbitrary code
    with the privileges of the user running the application. A local
    attacker could exploit the "dvilj" vulnerability to conduct a symlink
    attack to overwrite arbitrary files.
    </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 "&gt;=app-text/tetex-3.0_p1-r6"</code>
  </resolution>
