The DecodeTCPOptions function in decode.c in Snort before 2.3.0, when printing TCP/IP options using FAST output or verbose mode, allows remote attackers to cause a denial of service (crash) via packets with invalid TCP/IP options, which trigger a null dereference.

Security readout for executives and security teams

CVE-2004-2652 is a remote crash issue in Snort before 2.3.0. Specially malformed TCP/IP options could make Snort crash when certain output modes printed packet options, reducing monitoring coverage rather than directly compromising business data. Exposure is likely limited to legacy Snort deployments earlier than 2.3.0, especially sensors using FAST output or verbose mode. Modern supported Snort deployments are unlikely to be affected based on the version boundary provided. Address during legacy security-tool cleanup unless affected sensors protect high-value networks. The business risk is loss of detection visibility, not direct system takeover, but outages in monitoring can delay incident response. Mitigation focus: Upgrade Snort deployments older than 2.3.0 or follow current Snort vendor guidance.; Identify sensors using FAST output or verbose mode and prioritize them.; Reduce reliance on unsupported legacy Snort sensors for critical monitoring paths..
