Name of the Vulnerable Software and Affected Versions Suricata versions prior to 7.0.8

Description The issue is related to a buffer overflow in the BPF filter of the Suricata system, which can be exploited to cause a denial of service. A large BPF filter file provided to Suricata at startup can lead to this buffer overflow.

Recommendations For versions prior to 7.0.8, update to Suricata 7.0.8 to address the issue. As a temporary workaround, consider restricting the size of BPF filter files provided to Suricata at startup to minimize the risk of exploitation.
