Bug Fix(es) and Enhancement(s):

* [Rocky Linux 9.9] OpenSSL silently uses default provider when `fips.so` is missing on systems in FIPS mode (JIRA:Rocky Linux-239862)

* OpenSSL fails to initialize when automatic initialization happens in threads [Rocky Linux 9] (JIRA:Rocky Linux-256385)

Tenable has extracted the preceding description block directly from the CIQ security advisory.

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