The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:6346 advisory.

  • go-yaml: Improve heuristics preventing CPU/memory abuse by parsing malicious or large YAML documents (CVE-2022-3064)

  • net/http, golang.org/x/net/http2: avoid quadratic complexity in HPACK decoding (CVE-2022-41723)

  • golang: net/http, mime/multipart: denial of service from excessive resource consumption (CVE-2022-41725)

  • golang: net/http, net/textproto: denial of service from excessive memory allocation (CVE-2023-24534)

  • golang: net/http, net/textproto, mime/multipart: denial of service from excessive resource consumption (CVE-2023-24536)

  • golang: html/template: backticks not treated as string delimiters (CVE-2023-24538)

  • golang: html/template: improper sanitization of CSS values (CVE-2023-24539)

  • golang: html/template: improper handling of JavaScript whitespace (CVE-2023-24540)

  • golang: html/template: improper handling of empty HTML attributes (CVE-2023-29400)

  • golang: net/http: insufficient sanitization of Host header (CVE-2023-29406)

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