There are multiple vulnerabilities in versions of Ethereal earlier
|
|
than 0.10.9, including:
|
|
</p>
|
|
<ul>
|
|
<li>The COPS dissector could go into
|
|
an infinite loop (CAN-2005-0006).</li>
|
|
<li>The DLSw dissector could
|
|
cause an assertion, making Ethereal exit prematurely
|
|
(CAN-2005-0007).</li>
|
|
<li>The DNP dissector could cause memory
|
|
corruption (CAN-2005-0008).</li>
|
|
<li>The Gnutella dissector could cause
|
|
an assertion, making Ethereal exit prematurely (CAN-2005-0009).</li>
|
|
<li>The MMSE dissector could free statically-allocated memory
|
|
(CAN-2005-0010).</li>
|
|
<li>The X11 dissector is vulnerable to a string
|
|
buffer overflow (CAN-2005-0084).</li>
|
|
</ul>

<impact type="high">
|
|
<p>
|
|
An attacker might be able to use these vulnerabilities to crash
|
|
Ethereal, perform DoS by CPU and disk space utilization 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 version.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All Ethereal users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-analyzer/ethereal-0.10.9"</code>
|
|
