There are multiple vulnerabilities in versions of Ethereal earlier
|
|
than 0.10.8, including:
|
|
</p>
|
|
<ul>
|
|
<li>Bug in DICOM dissection
|
|
discovered by Bing could make Ethereal crash (CAN 2004-1139).</li>
|
|
<li>An invalid RTP timestamp could make Ethereal hang and create a
|
|
large temporary file (CAN 2004-1140).</li>
|
|
<li>The HTTP dissector could
|
|
access previously-freed memory (CAN 2004-1141).</li>
|
|
<li>Brian Caswell
|
|
discovered that an improperly formatted SMB could make Ethereal hang
|
|
(CAN 2004-1142).</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-0.10.8"</code>
|
|
</resolution>
