    <p>
    Ethereal is a feature rich network protocol analyzer.

  <description>
    <p>
    There are multiple vulnerabilities in versions of Ethereal earlier than
    0.10.4, including:
    </p>
    <ul>
    <li>A buffer overflow in the MMSE dissector.</li>
    <li>Under specific conditions a SIP packet could make Ethereal
    crash.</li>
    <li>The AIM dissector could throw an assertion, causing Ethereal to
    crash.</li>
    <li>The SPNEGO dissector could dereference a null pointer, causing a
    crash.</li>
    </ul>
  </description>
  <impact type="high">
    <p>
    An attacker could use these vulnerabilities to crash Ethereal or even
    execute arbitrary code with the permissions of the user running
    Ethereal, which could be the root user.
    </p>
  </impact>
  <workaround>
    <p>
    For a temporary workaround you can disable all affected protocol
    dissectors by selecting Analyze-&gt;Enabled Protocols... and deselecting
    them from the list. However, it is strongly recommended to upgrade to
    the latest stable release.
    </p>
  </workaround>
  <resolution>
    <p>
    All Ethereal users should upgrade to the latest stable version:
    </p>
    <code>
    # emerge sync
    
    # emerge -pv "&gt;=net-analyzer/ethereal-0.10.4"
    # emerge "&gt;=net-analyzer/ethereal-0.10.4"</code>
  </resolution>
