<title>Snort: Remote execution of arbitrary code</title>
The Snort DCE/RPC preprocessor contains a buffer overflow that could result
in the remote execution of arbitrary code.

Snort is a widely deployed intrusion detection program.
The Snort DCE/RPC preprocessor does not properly reassemble certain
types of fragmented SMB and DCE/RPC packets.
<impact type="high">
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.
Disable the DCE/RPC processor by commenting the 'preprocessor dcerpc'
section in /etc/snort/snort.conf .
All Snort users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-analyzer/snort-;</code>
