  <title>Wireshark: Multiple vulnerabilities</title>
  <synopsis>
    Multiple vulnerabilities have been discovered in Wireshark, allowing for
    the remote execution of arbitrary code and a Denial of Service.

    <p>
    Wireshark is a network protocol analyzer with a graphical front-end.
    </p>

  <description>
    <p>
    Wireshark doesn't properly handle chunked encoding in HTTP responses
    (CVE-2007-3389), iSeries capture files (CVE-2007-3390), certain types
    of DCP ETSI packets (CVE-2007-3391), and SSL or MMS packets
    (CVE-2007-3392). An off-by-one error has been discovered in the
    DHCP/BOOTP dissector when handling DHCP-over-DOCSIS packets
    (CVE-2007-3393).
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could send specially crafted packets on a network
    being monitored with Wireshark, possibly resulting in the execution of
    arbitrary code with the privileges of the user running Wireshark which
    might be the root user, or a Denial of Service.
    </p>
  </impact>
  <workaround>
    <p>
    In order to prevent root compromise, take network captures with tcpdump
    and analyze them running Wireshark as a least privileged user.
    </p>
  </workaround>
  <resolution>
    <p>
    All Wireshark users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=net-analyzer/wireshark-0.99.6&quot;</code>
  </resolution>
