  <background>
    <p>The JasPer Project is an open-source initiative to provide a free
      software-based reference implementation of the codec specified in the
      JPEG-2000 Part-1 (jpeg2k) standard.
    </p>
  </background>
  <description>
    <p>Two vulnerabilities have been found in JasPer:</p>
    
    <ul>
      <li>The jpc_cox_getcompparms function in libjasper/jpc/jpc_cs.c contains
        an error that could overwrite certain callback pointers, possibly
        causing a heap-based buffer overflow (CVE-2011-4516).
      </li>
      <li>The jpc_crg_getparms function in libjasper/jpc/jpc_cs.c uses an
        incorrect data type, possibly causing a heap-based buffer overflow
        (CVE-2011-4517).
      </li>
    </ul>
  </description>
  <impact type="normal">
    <p>A remote attacker could entice a user or automated system to process
      specially crafted JPEG-2000 files with an application using JasPer,
      possibly resulting in the execution of arbitrary code with the privileges
      of the application, or a Denial of Service.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All JasPer users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=media-libs/jasper-1.900.1-r4"
    </code>
