+ <background>
+ <p>
+ Ethereal is a feature rich network protocol analyzer.
+ </p>
+ </background>
+ <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>
