The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2023:4523 advisory.

  - An authentication bypass vulnerability exists libcurl <8.0.0 in the connection reuse feature which can     reuse previously established connections with incorrect user permissions due to a failure to check for     changes in the CURLOPT_GSSAPI_DELEGATION option. This vulnerability affects krb5/kerberos/negotiate/GSSAPI     transfers and could potentially result in unauthorized access to sensitive information. The safest option     is to not reuse connections if the CURLOPT_GSSAPI_DELEGATION option has been changed. (CVE-2023-27536)

  - An improper certificate validation vulnerability exists in curl <v8.1.0 in the way it supports matching of     wildcard patterns when listed as Subject Alternative Name in TLS server certificates. curl can be built     to use its own name matching function for TLS rather than one provided by a TLS library. This private     wildcard matching function would match IDN (International Domain Name) hosts incorrectly and could as a     result accept patterns that otherwise should mismatch. IDN hostnames are converted to puny code before     used for certificate checks. Puny coded names always start with `xn--` and should not be allowed to     pattern match, but the wildcard check in curl could still check for `x*`, which would match even though     the IDN name most likely contained nothing even resembling an `x`. (CVE-2023-28321)

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