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

  <description>
    <p>
    There are multiple vulnerabilities in versions of Ethereal earlier than
    0.10.5, including:
    </p>
    <ul>
    <li>In some cases the iSNS dissector could cause Ethereal to
    abort.</li>
    <li>If there was no policy name for a handle for SMB SID snooping it
    could cause a crash.</li>
    <li>A malformed or missing community string could cause the SNMP
    dissector to 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->Enabled Protocols... and deselecting
    them from the list. For SMB you can disable SID snooping in the SMB
    protocol preference. However, it is strongly recommended to upgrade to
    the latest stable version.
    </p>
  </workaround>
  <resolution>
    <p>
    All Ethereal users should upgrade to the latest stable version:
    </p>
    <code>
    # emerge sync
    
    # emerge -pv &quot;&gt;=net-analyzer/ethereal-0.10.5&quot;
    # emerge &quot;&gt;=net-analyzer/ethereal-0.10.5&quot;</code>
