The remote Redhat Enterprise Linux 8 / 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:4093 advisory.
kube-apiserver: PrivEsc (CVE-2023-1260)
openshift: OCP & FIPS mode (CVE-2023-3089)
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: go/parser: Infinite loop in parsing (CVE-2023-24537)
golang: html/template: backticks not treated as string delimiters (CVE-2023-24538)
golang: html/template: improper sanitization of CSS values (CVE-2023-24539)
runc: volume mount race condition (regression of CVE-2019-19921) (CVE-2023-27561)
golang: html/template: improper handling of empty HTML attributes (CVE-2023-29400)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
