Name of the Vulnerable Software and Affected Versions Suricata versions prior to 8.0.1

Description Suricata, a network IDS, IPS and NSM engine, experiences a segmentation fault when processing decoded subjectaltnames containing a NULL byte. This occurs due to the use of the tls.subjectaltname keyword in version 8.0.0. Disabling rules that utilize the tls.subjectaltname keyword can serve as a temporary workaround.
