Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to incorrect handling of TCP streams with TCP urgent data (out of band data), which can lead to Suricata analyzing data differently than the applications at the TCP endpoints. A remote attacker can bypass generic detection when using TCP urgent support.
