  <title>JasPer: User-assisted execution of arbitrary code</title>
  <synopsis>
    Multiple memory management errors in JasPer might lead to execution of
    arbitrary code via jpeg2k files.

  <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>

  <description>
    <p>
    Marc Espie and Christian Weisgerber have discovered multiple
    vulnerabilities in JasPer:
    </p>
    <ul>
    <li>
    Multiple integer overflows might allow for insufficient memory
    allocation, leading to heap-based buffer overflows (CVE-2008-3520).
    </li>
    <li>
    The jas_stream_printf() function in libjasper/base/jas_stream.c uses
    vsprintf() to write user-provided data to a static to a buffer, leading
    to an overflow (CVE-2008-3522).
    </li>
    </ul>
  </description>
  <impact type="normal">
    <p>
    Remote attackers could entice a user or automated system to process
    specially crafted jpeg2k files with an application using JasPer,
    possibly leading to the execution of arbitrary code.
    </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-r3"</code>
  </resolution>
