[GLSA-200703-01] Snort: Remote execution of arbitrary code Vulnerability Scan
Vulnerability Scan Summary
Snort: Remote execution of arbitrary code
Detailed Explanation for this Vulnerability Test
The remote host is affected by the vulnerability described in GLSA-200703-01
(Snort: Remote execution of arbitrary code)
The Snort DCE/RPC preprocessor does not properly reassemble certain
types of fragmented SMB and DCE/RPC packets.
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 'preprocessor rpc_decode'
and 'include $RULE_PATH/rpc.rules' from /etc/snort/snort.conf .
All Snort users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-analyzer/snort-188.8.131.52"
Threat Level: High
