Suricata is a network IDS, IPS and NSM engine. While saving a dataset a stack buffer is used to prepare the data. Prior to versions 8.0.3 and 7.0.14, if the data in the dataset is too large, this can result in a stack overflow. Versions 8.0.3 and 7.0.14 contain a patch. As a workaround, do not use rules with datasets `save` nor `state` options.

suricata: Suricata: Denial of service due to stack overflow when saving large datasets
Suricata is a network IDS, IPS and NSM engine. While saving a dataset a stack buffer is used to prepare the data. Prior to versions 8.0.3 and 7.0.14, if the data in the dataset is too large, this can result in a stack overflow. Versions 8.0.3 and 7.0.14 contain a patch. As a workaround, do not use rules with datasets `save` nor `state` options.
A flaw was found in Suricata, a network intrusion detection/prevention system (IDS/IPS). When saving a dataset, the system uses a stack buffer to process the data. If an attacker provides excessively large data within a dataset, it can cause a stack overflow. This vulnerability could lead to a denial of service, making the system unavailable.
