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-2024:1082 advisory.

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

    CVE-2024-47522:
    Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security     Monitoring engine. Prior to version 7.0.7, invalid ALPN in TLS/QUIC traffic when JA4 matching/logging is     enabled can lead to Suricata aborting with a panic. This issue has been addressed in 7.0.7. One may     disable ja4 as a workaround.

    CVE-2024-45795:
    Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security     Monitoring engine. Prior to version 7.0.7, missing initialization of the random seed for thash leads to     byte-range tracking having predictable hash table behavior. This can lead to an attacker forcing lots of     data into a single hash bucket, leading to severe performance degradation. This issue has been addressed     in 7.0.7.

    CVE-2024-47187:
    Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security     Monitoring engine. Prior to version 7.0.7, missing initialization of the random seed for thash leads to     datasets having predictable hash table behavior. This can lead to dataset file loading to use excessive     time to load, as well as runtime performance issues during traffic handling. This issue has been addressed     in 7.0.7. As a workaround, avoid loading datasets from untrusted sources. Avoid dataset rules that track     traffic in rules.

    CVE-2024-47188:
    Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security     Monitoring engine. Prior to version 7.0.7, a logic error during fragment reassembly can lead to failed     reassembly for valid traffic.

    Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security     Monitoring engine.  Prior to 7.0.3, the rules inspecting HTTP2 headers can get bypassed by crafted     traffic. The vulnerability has been patched in 7.0.3.

    CVE-2024-23839:
    Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security     Monitoring engine.  Prior to 7.0.3, specially crafted traffic can cause a heap use after free if the     ruleset uses the http.request_header or http.response_header keyword.  The vulnerability has been patched     in 7.0.3.  To work around the vulnerability, avoid the http.request_header and http.response_header     keywords.

    CVE-2024-23835:
    Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security     Monitoring engine.  Prior to version 7.0.3, excessive memory use during pgsql parsing could lead to OOM-     related crashes.  This vulnerability is patched in 7.0.3.  As workaround, users can disable the pgsql app     layer parser.

    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, 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-2024-23836:
    Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security     Monitoring engine. Prior to versions 6.0.16 and 7.0.3, an attacker can craft traffic to cause Suricata to     use far more CPU and memory for processing the traffic than needed, which can lead to extreme slow downs     and denial of service.  This vulnerability is patched in 6.0.16 or 7.0.3.  Workarounds include disabling     the affected protocol app-layer parser in the yaml and reducing the `stream.reassembly.depth` value helps     reduce the severity of the issue.
