"The remote Fedora 38 host has a package installed that is affected by multiple vulnerabilities as referenced in the
FEDORA-2024-7b063bce0a advisory.

  - 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-2024-24568)

  - 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-2024-23835)

  - 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. (CVE-2024-23836)

  - LibHTP is a security-aware parser for the HTTP protocol. Crafted traffic can cause excessive processing
    time of HTTP headers, leading to denial of service. This issue is addressed in 0.5.46. (CVE-2024-23837)

  - 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-2024-23839)

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