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

<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>
