Name of the Vulnerable Software and Affected Versions Suricata versions prior to 8.0.3 Suricata versions prior to 7.0.14

Description Suricata is a network IDS, IPS and NSM engine. A stack buffer overflow can occur while saving a dataset due to the use of a stack buffer to prepare the data. If the data in the dataset is too large, this can lead to a stack overflow. Exploitation of this issue may allow a remote attacker to cause a denial of service or potentially achieve code execution.

Recommendations Update Suricata to version 8.0.3 or later. Update Suricata to version 7.0.14 or later. As a workaround, do not use rules with datasets save nor state options.
