Suricata 8.x < 8.0.2 Multiple Vulnerabilities

high Nessus Plugin ID 277498

Synopsis

An IDS/IPS solution running on the remote host is affected by multiple vulnerabilities.

Description

The version of OISF Suricata installed on the remote host is 8.x prior to 8.0.2. It is, therefore, affected by multiple vulnerabilities:

 - 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, compressed HTTP data can lead to unbounded memory growth during decompression. This issue has been patched in version 8.0.2. A workaround involves disabling LZMA decompression or limiting response-body-limit size. (CVE-2025-64334)

 - 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. (CVE-2025-64335)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade Suricata to version 8.0.2 or higher.
