  <title>Xpdf, GPdf: New integer overflows</title>
  <synopsis>
    New integer overflows were discovered in Xpdf, potentially resulting in the
    execution of arbitrary code. GPdf includes Xpdf code and therefore is
    vulnerable to the same issues.

  <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 or GPdf.
    </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-r7"</code>
    <p>
    All GPdf users should also upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=app-text/gpdf-2.8.1-r1"</code>
