CVE-2003-0209 describes a critical integer overflow vulnerability in the TCP stream reassembly module (stream4) of Snort 2.0 and earlier, affecting products like Smoothwall and Sourcefire Snort. This flaw allows remote attackers to execute arbitrary code by manipulating large sequence numbers in packets, leading to a heap-based buffer overflow. With a CVSS score of 10.0, it represents a severe risk due to its network-based attack vector, low complexity, and complete compromise of confidentiality, integrity, and availability. While not on CISA's KEV catalog, an ExploitDB entry (EDB-18) confirms the existence of remote command execution exploit code, though there is minimal community discussion or media coverage.
