<description>
<p>
There are multiple vulnerabilities in versions of Ethereal earlier than
0.10.4, including:
</p>
<ul>
<li>A buffer overflow in the MMSE dissector.</li>
<li>Under specific conditions a SIP packet could make Ethereal
crash.</li>
<li>The AIM dissector could throw an assertion, causing Ethereal to
crash.</li>
<li>The SPNEGO dissector could dereference a null pointer, causing a
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. However, it is strongly recommended to upgrade to
the latest stable release.
</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-0.10.4&quot;
# emerge &quot;&gt;=net-analyzer/ethereal-0.10.4&quot;</code>
</resolution>
