Severity: High Title: Snort: Remote execution of arbitrary code Date: February 23, 2007 Bugs: #167730 ID: 200703-01

Synopsis ========
The Snort DCE/RPC preprocessor contains a buffer overflow that could result in the remote execution of arbitrary code.
Background ==========
Snort is a widely deployed intrusion detection program.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-analyzer/snort < 2.6.1.3 >= 2.6.1.3
Description ===========
The Snort DCE/RPC preprocessor does not properly reassemble certain types of fragmented SMB and DCE/RPC packets.
Impact ======
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.
Workaround ==========
Disable the DCE/RPC processor by commenting 'preprocessor rpc_decode' and 'include $RULE_PATH/rpc.rules' from /etc/snort/snort.conf .
Resolution ==========
All Snort users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-analyzer/snort-2.6.1.3"
References ==========
