Background
Suricata is an intrusion detection tool that is used to monitor network traffic and detect potential threats. It is designed to analyze packets and identify suspicious activity. However, a vulnerability has been discovered in Suricata that could allow an attacker to create a packet that would not be re-assembled by the destination host. This vulnerability arises from the IP protocol not being used to match fragments with their packets, enabling a carefully constructed packet with a different protocol to be matched.
