NVD Description

Note: Versions mentioned in the description apply only to the upstream suricata package and not the suricata package as distributed by Debian. See How to fix? for Debian:13 relevant fixed versions and status.

Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community. In versions from 8.0.0 to before 8.0.2, a NULL dereference can occur when the entropy keyword is used in conjunction with base64_data. This issue has been patched in version 8.0.2. A workaround involves disabling rules that use entropy in conjunction with base64_data.
