Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community. Versions 7.0.11 and below, as well as 8.0.0, are vulnerable to detection bypass when crafted traffic sends multiple SYN packets with different sequence numbers within the same flow tuple, which can cause Suricata to fail to pick up the TCP session. In IDS mode this can lead to a detection and logging bypass. In IPS mode this will lead to the flow getting blocked. This issue is fixed in versions 7.0.12 and 8.0.1.

The remote Fedora 43 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2025-00748128e3 advisory.

The version of OISF Suricata installed on the remote host is 8.0.x prior to 8.0.1. 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. Versions 8.0.0 and below incorrectly handle the entropy keyword     when not anchored to a 'sticky' buffer, which can lead to a segmentation fault. This issue is fixed in     version 8.0.1. To workaround this issue, users can disable rules using the entropy keyword, or validate     they are anchored to a sticky buffer. (CVE-2025-59148)     
  - Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security     Foundation) and the Suricata community. In version 8.0.0, rules using keyword     ldap.responses.attribute_type (which is long) with transforms can lead to a stack buffer overflow during     Suricata startup or during a rule reload. This issue is fixed in version 8.0.1. To workaround this issue,     users can disable rules with ldap.responses.attribute_type and transforms. (CVE-2025-59149)     
  - Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security     Foundation) and the Suricata community. Version 8.0.0's usage of the tls.subjectaltname keyword can lead     to a segmentation fault when the decoded subjectaltname contains a NULL byte. This issue is fixed in     version 8.0.1. To workaround this issue, disable rules using the tls.subjectaltname keyword.     (CVE-2025-59150)

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.
