patch available.

  - Wasmtime is a standalone runtime for WebAssembly. Prior to versions 2.0.2 and 1.0.2, there is a bug in
    Wasmtime's implementation of its pooling instance allocator where when a linear memory is reused for
    another instance the initial heap snapshot of the prior instance can be visible, erroneously to the next
    instance. This bug has been patched and users should upgrade to Wasmtime 2.0.2 and 1.0.2. Other
    mitigations include disabling the pooling allocator and disabling the `memory-init-cow`. (CVE-2022-39393)

Note that Nessus relies on the presence of the package as reported by the vendor.");
