There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security
    Monitoring engine. Prior to 7.0.8, a large input buffer to the to_lowercase, to_uppercase,
    strip_whitespace, compress_whitespace, dotprefix, header_lowercase, strip_pseudo_headers, url_decode, or
    xor transform can lead to a stack overflow causing Suricata to crash. The issue has been addressed in
    Suricata 7.0.8. (CVE-2024-55605)

  - Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security
    Monitoring engine. Prior to 7.0.8, a large BPF filter file provided to Suricata at startup can lead to a
    buffer overflow at Suricata startup. The issue has been addressed in Suricata 7.0.8. (CVE-2024-55626)

  - Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security
    Monitoring engine. Prior to 7.0.8, a specially crafted TCP stream can lead to a very large buffer overflow
    while being zero-filled during initialization with memset due to an unsigned integer underflow. The issue
    has been addressed in Suricata 7.0.8. (CVE-2024-55627)

  - Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security
    Monitoring engine. Prior to version 7.0.8, DNS resource name compression can lead to small DNS messages
    containing very large hostnames which can be costly to decode, and lead to very large DNS log records.
    While there are limits in place, they were too generous. The issue has been addressed in Suricata 7.0.8.
    (CVE-2024-55628)

  - Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security
    Monitoring engine. Prior to 7.0.8, TCP streams with TCP urgent data (out of band data) can lead to
    Suricata analyzing data differently than the applications at the TCP endpoints, leading to possible
    evasions. Suricata 7.0.8 includes options to allow users to configure how to handle TCP urgent data. In
    IPS mode, you can use a rule such as drop tcp any any -> any any (sid:1; tcp.flags:U*;) to drop all the
    packets with urgent flag set. (CVE-2024-55629)

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-2025:0025 advisory.

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

    CVE-2024-55628:
    Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security     Monitoring engine. Prior to version 7.0.8, DNS resource name compression can lead to small DNS messages     containing very large hostnames which can be costly to decode, and lead to very large DNS log records.
    While there are limits in place, they were too generous. The issue has been addressed in Suricata 7.0.8.

    CVE-2024-55605:
    Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security     Monitoring engine. Prior to 7.0.8, a large input buffer to the to_lowercase, to_uppercase,     strip_whitespace, compress_whitespace, dotprefix, header_lowercase, strip_pseudo_headers, url_decode, or     xor transform can lead to a stack overflow causing Suricata to crash. The issue has been addressed in     Suricata 7.0.8.

    CVE-2024-55629:
    Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security     Monitoring engine. Prior to 7.0.8, TCP streams with TCP urgent data (out of band data) can lead to     Suricata analyzing data differently than the applications at the TCP endpoints, leading to possible     evasions. Suricata 7.0.8 includes options to allow users to configure how to handle TCP urgent data.

    CVE-2024-55626:
    Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security     Monitoring engine. Prior to 7.0.8, a large BPF filter file provided to Suricata at startup can lead to a     buffer overflow at Suricata startup. The issue has been addressed in Suricata 7.0.8.

    CVE-2024-55627:
    Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security     Monitoring engine. Prior to 7.0.8, a specially crafted TCP stream can lead to a very large buffer overflow     while being zero-filled during initialization with memset due to an unsigned integer underflow. The issue     has been addressed in Suricata 7.0.8.

    CVE-2024-32867:
    Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security     Monitoring engine. Prior to 7.0.5 and 6.0.19, various problems in handling of fragmentation anomalies can     lead to mis-detection of rules and policy. This vulnerability is fixed in 7.0.5 or 6.0.19.

    CVE-2024-32663:
    Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security     Monitoring engine. Prior to 7.0.5 and 6.0.19, a small amount of HTTP/2 traffic can lead to Suricata using     a large amount of memory. The issue has been addressed in Suricata 7.0.5 and 6.0.19. Workarounds include     disabling the HTTP/2 parser and reducing `app-layer.protocols.http2.max-table-size` value (default is     65536).

    CVE-2024-28870:
    Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security     Monitoring engine developed by the OISF and the Suricata community. When parsing an overly long SSH     banner, Suricata can use excessive CPU resources, as well as cause excessive logging volume in alert     records. This issue has been patched in versions 6.0.17 and 7.0.4.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

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

The version of OISF Suricata installed on the remote host is prior to 6.0.19 or 7.x prior to 7.0.5. It is, therefore, affected by multiple vulnerabilities: 

  - A large input buffer to one of the following transforms can lead to a stack overflow causing Suricata to     crash in the following transforms: to_lowercase, to_uppercase, strip_whitespace, compress_whitespace, dotprefix,     header_lowercase, strip_pseudo_headers, url_decode, xor (CVE-2024-55605)     
  - A large BPF filter file provided to Suricata at startup can lead to a buffer overflow at Suricata startup.     (CVE-2024-55626)     
  - A specially crafted TCP stream can lead to a very large buffer overflow while being zero-filled during     initialization with memset due to an unsigned integer underflow. (CVE-2024-55627)

Note that Nessus has not tested for this issue 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.

  - Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security     Monitoring engine. Prior to version 7.0.8, DNS resource name compression can lead to small DNS messages     containing very large hostnames which can be costly to decode, and lead to very large DNS log records.
    While there are limits in place, they were too generous. The issue has been addressed in Suricata 7.0.8.
    (CVE-2024-55628)

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