<p>
Wireshark is a feature-rich network protocol analyzer.

<description>
<p>
The following vulnerabilities have been discovered in Wireshark.
Firstly, if the IPsec ESP parser is used it is susceptible to
off-by-one errors, this parser is disabled by default; secondly, the
SCSI dissector is vulnerable to an unspecified crash; and finally, the
Q.2931 dissector of the SSCOP payload may use all the available memory
if a port range is configured. By default, no port ranges are
configured.
</p>
</description>
<impact type="normal">
<p>
An attacker might be able to exploit these vulnerabilities, resulting
in a crash or the execution of arbitrary code with the permissions of
the user running Wireshark, possibly the root user.
</p>
</impact>
<workaround>
<p>
Disable the SCSI and Q.2931 dissectors with the "Analyse" and "Enabled
protocols" menus. Make sure the ESP decryption is disabled, with the
"Edit -> Preferences -> Protocols -> ESP" menu.
</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-0.99.3&quot;</code>
</resolution>
