TCP: Options Error Option Too Long
This protocol anomaly triggers when it detects an option that specifies a length longer than the length of the entire options buffer. Because this can indicate a buffer overflow or another exploit attempt, it is recommended to drop these packets.
Extended Description
The presence of malformed TCP option headers in network traffic could indicate a network configuration error or that a malicious party is attempting to conduct a denial of service or other attack.
