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. Mishandling of multiple fragmented packets using the same IP ID value can lead to
    packet reassembly failure, which can lead to policy bypass. Upgrade to 7.0.6 or 6.0.20. When using af-
    packet, enable `defrag` to reduce the scope of the problem. (CVE-2024-37151)

  - 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-2024-32663)

  - Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security
    Monitoring engine. Prior to 7.0.5 and 6.0.19, specially crafted traffic or datasets can cause a limited
    buffer overflow. This vulnerability is fixed in 7.0.5 and 6.0.19. Workarounds include not use rules with
    `base64_decode` keyword with `bytes` option with value 1, 2 or 5 and for 7.0.x, setting `app-
    layer.protocols.smtp.mime.body-md5` to false. (CVE-2024-32664)

  - 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-2024-32867)

An update of the suricata package has been released.

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. 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-2024-55626:
    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: 

  - In affected versions, specially crafted traffic or datasets can cause a limited buffer overflow.     (CVE-2024-32664)     
  - In affected versions, a small amount of HTTP/2 traffic can lead to Suricata using a large amount of memory.
    (CVE-2024-32663)     
  - In affected versions, various problems in handling of fragmentation anomalies can lead to mis-detection of rules     and policy. (CVE-2024-32867)

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

The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-4103 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.
