|
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 ">=net-analyzer/ethereal-0.10.4"

# emerge ">=net-analyzer/ethereal-0.10.4"</code>
