  <title>Xpdf, CUPS: Multiple integer overflows</title>
  <synopsis>
    Multiple integer overflows were discovered in Xpdf, potentially resulting
    in execution of arbitrary code upon viewing a malicious PDF file. CUPS
    includes Xpdf code and therefore is vulnerable to the same issues.

    Xpdf is an open source viewer for Portable Document Format (PDF) files. The
    Common UNIX Printing System (CUPS) is a cross-platform print spooler that
    includes some Xpdf code.

    Chris Evans discovered multiple integer overflow issues in Xpdf.

  <impact type="normal">
    <p>
    An attacker could entice an user to open a specially-crafted PDF file,
    potentially resulting in execution of arbitrary code with the rights of the
    user running Xpdf. By enticing an user to directly print the PDF file to a
    CUPS printer, an attacker could also crash the CUPS spooler or execute
    arbitrary code with the rights of the CUPS spooler, which is usually the
    "lp" user.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Xpdf users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=app-text/xpdf-3.00-r5"</code>
    <p>
    All CUPS users should also upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=net-print/cups-1.1.20-r5"</code>
