• Severity: critical (CVSS 9.8 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.6% probability of exploitation in the next 30 days
• Public exploit or detection template: none known

Description

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.

Affected products

• OISF suricata: before 7.0.14; from 8.0.0 before 8.0.3 — fixed in 7.0.14, 8.0.3

How to fix

Upgrade to a fixed version: OISF suricata 7.0.14, 8.0.3. Check the vendor advisory for mitigations.
