CVE-2003-0209
HighSummary
Integer overflow in the TCP stream reassembly module (stream4) for Snort 2.0 and earlier allows remote attackers to execute arbitrary code via large sequence numbers in packets, leading to a heap-based buffer overflow.
Risk Assessment
Attackers can remotely gain control over the system, posing a serious security threat to the organization. Exploiting this vulnerability may lead to data loss or unauthorized access to systems.
Recommendation
It is recommended to update Snort to the latest version to mitigate this vulnerability. Additionally, monitoring network traffic for suspicious packets can help minimize risk.
