<p>
Ethereal is a popular network protocol analyzer.
</p>
</background>
<description>
<p>
Ethereal contains buffer overflow vulnerabilities in the GTP, ISAKMP, and
MEGACO protocol dissectors, and a heap overflow vulnerability in the SOCKS
protocol dissector, which could cause Ethereal to crash or to execute
arbitrary code.
</p>
</description>
<impact type="normal">
<p>
A remote attacker could craft a malformed packet which would cause Ethereal
to crash or run arbitrary code with the permissions of the user running
Ethereal.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time, other than to disable the GTP,
ISAKMP, MEGACO, and SOCKS protocol dissectors.
</p>
</workaround>
<resolution>
<p>
It is recommended that all Gentoo Linux users who are running
net-analyzer/ethereal 0.9.x upgrade:
</p>
<code>
# emerge sync
# emerge -pv '>=net-analyzer/ethereal-0.9.16'
# emerge '>=net-analyzer/ethereal-0.9.16'
# emerge clean</code>
</resolution>
