<p>
|
|
The Snort DCE/RPC preprocessor does not properly reassemble certain
|
|
types of fragmented SMB and DCE/RPC packets.
|
|
</p>
|
|
</description>
|
|
<impact type="high">
|
|
<p>
|
|
A remote attacker could send specially crafted fragmented SMB or
|
|
DCE/RPC packets, without the need to finish the TCP handshake, that
|
|
would trigger a stack-based buffer overflow while being reassembled.
|
|
This could lead to the execution of arbitrary code with the permissions
|
|
of the user running the Snort preprocessor.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
Disable the DCE/RPC processor by commenting the 'preprocessor dcerpc'
|
|
section in /etc/snort/snort.conf .
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All Snort users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-analyzer/snort-2.6.1.3"</code>
