The version of rust / tensorflow / cmake / mysql installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2023-27537 advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

- A double free vulnerability exists in libcurl <8.0.0 when sharing HSTS data between separate handles.
This sharing was introduced without considerations for do this sharing across separate threads but there
was no indication of this fact in the documentation. Due to missing mutexes or thread locks, two threads
sharing the same HSTS data could end up doing a double-free or use-after-free. (CVE-2023-27537)
