遠端主機上安裝的 OISF Suricata 版本低於 6.0.17，或為低於 7.0.4 的 7.x 版。因此，會受到一個拒絕服務 (DoS) 弱點影響。剖析過長的 SSH 標題時，Suricata 會使用過量的 CPU 資源，並造成警示記錄中的記錄容量過大。

請注意，Nessus 並未測試此問題，而是僅依據應用程式自我報告的版本號碼作出判斷。

远程主机上安装的 OISF Suricata 低于 6.0.17 版或为低于 7.0.4 的 7.x 版。因而会受到拒绝服务 (DoS) 漏洞的影响。解析过长的 SSH 标题时，Suricata 会使用过多 CPU 资源，并造成警报记录中出现过多的日志记录卷。

请注意，Nessus 尚未测试此问题，而是只依据应用程序自我报告的版本号进行判断。

Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且供應商未提供可用的修補程式。

  - Suricata 是由 OISF 和 Suricata 社區開發的網絡入侵檢測系統、入侵防禦系統和網絡安全監控引擎。剖析過長的 SSH 標題時，Suricata 會使用過量的 CPU 資源，並造成警示記錄中的記錄容量過大。此問題已在 6.0.17、7.0.4 和 CVE-2024-28870 版本中修正。

請注意，Nessus 的判定取決於廠商所報告的套件是否存在。

Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。

  - Suricata 是由 OISF 和 Suricata 社区开发的网络入侵检测系统、入侵防护系统和网络安全监控引擎。解析过长的 SSH 标题时，Suricata 会使用过多 CPU 资源，并造成警报记录中出现过多的日志记录卷。已在版本 6.0.17 和 7.0.4 中修补此问题。(CVE-2024-28870)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。

Linux/Unix ホストには、ベンダーが提供するパッチが利用できない脆弱性の影響を受ける複数のパッケージがインストールされています。

  - Suricata は、OISF と Suricata コミュニティによって開発された、ネットワーク侵入検知システム、侵入防止システム、およびネットワークセキュリティ監視エンジンです。過度に長い SSH バナーを解析すると、Suricata は過剰な CPU リソースを使用し、アラートレコードのログ量が過剰になる可能性があります。この問題には、バージョン 6.0.17および 7.0.4でパッチが適用されています。(CVE-2024-28870)

Nessus は、ベンダーによって報告されたパッケージの存在に依存していることに注意してください。

リモートホストにインストールされている OISF Suricata のバージョンは 6.0.17 より前、または 7.0.4 より前の 7.x です。したがって、サービス拒否（DoS） の脆弱性の影響を受けます。過度に長い SSH バナーを解析すると、Suricata は過剰な CPU リソースを使用し、アラートレコードのログ量が過剰になる可能性があります。

Nessus はこの問題をテストしておらず、代わりにアプリケーションが自己報告するバージョン番号にのみ依存していることに注意してください。

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 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. (CVE-2024-28870)

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

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 6.0.17 or 7.x prior to 7.0.4. It is, therefore, affected by a denial of service (DoS) vulnerability. When parsing an overly long SSH banner, Suricata can use excessive CPU resources, as well as cause excessive logging volume in alert records.

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