The remote Fedora 40 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2025-2a295896e6 advisory.

    This is an extra release to address a critical issue in 7.0.9 affecting AF_PACKET users: setting a BPF     would cause Suricata to fail to start up. This has been fixed.

    ----

    Various security, performance, accuracy, and stability issues have been fixed. LibHTP has been updated to     version 0.5.50 which is bundled with this new release. This fixes:

    CVE-2025-29915: HIGH     CVE-2025-29917: HIGH     CVE-2025-29918: HIGH     CVE-2025-29916: Moderate

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

  - Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security     Monitoring engine. A PCRE rule can be written that leads to an infinite loop when negated PCRE is used.
    Packet processing thread becomes stuck in infinite loop limiting visibility and availability in inline     mode. This vulnerability is fixed in 7.0.9. (CVE-2025-29918)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2025:0285 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2025-29918:
    Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security     Monitoring engine. A PCRE rule can be written that leads to an infinite loop when negated PCRE is used.
    Packet processing thread becomes stuck in infinite loop limiting visibility and availability in inline     mode. This vulnerability is fixed in 7.0.9.

    CVE-2025-29917:
    Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security     Monitoring engine. The bytes setting in the decode_base64 keyword is not properly limited. Due to this,     signatures using the keyword and setting can cause large memory allocations of up to 4 GiB per thread.
    This vulnerability is fixed in 7.0.9.

    CVE-2025-29916:
    Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security     Monitoring engine. Datasets declared in rules have an option to specify the `hashsize` to use. This size     setting isn't properly limited, so the hash table allocation can be large. Untrusted rules can lead to     large memory allocations, potentially leading to denial of service due to resource starvation. This     vulnerability is fixed in 7.0.9.

    CVE-2025-29915:
    Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security     Monitoring engine. The AF_PACKET defrag option is enabled by default and allows AF_PACKET to re-assemble     fragmented packets before reaching Suricata. However the default packet size in Suricata is based on the     network interface MTU which leads to Suricata seeing truncated packets. Upgrade to Suricata 7.0.9, which     uses better defaults and adds warnings for user configurations that may lead to issues.

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 1d53db32-0d60-11f0-8542-b42e991fc52e advisory.

    Several issues have been found in suricata, the next Generation Intrusion     Detection and Prevention Tool. They are related to bypass of HTTP-based     signature, mishandling of multiple fragmented packets, logic errors,     infinite loops, buffer overflows, unintended file access and using large     amount of memory.



    For Debian 11 bullseye, these problems have been fixed in version     1:6.0.1-3+deb11u1.

    We recommend that you upgrade your suricata packages.
