CVE-2025-64335

Suricata is vulnerable to a null deref when used with base64_data

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 base64data. This issue has been patched in version 8.0.2. A workaround involves disabling rules that use entropy in conjunction with base64data.
