patch available.

  - Wasmtime is a standalone runtime for WebAssembly. Prior to version 2.0.2, there is a bug in Wasmtime's C
    API implementation where the definition of the `wasmtime_trap_code` does not match its declared signature
    in the `wasmtime/trap.h` header file. This discrepancy causes the function implementation to perform a
    4-byte write into a 1-byte buffer provided by the caller. This can lead to three zero bytes being written
    beyond the 1-byte location provided by the caller. This bug has been patched and users should upgrade to
    Wasmtime 2.0.2. This bug can be worked around by providing a 4-byte buffer casted to a 1-byte buffer when
    calling `wasmtime_trap_code`. Users of the `wasmtime` crate are not affected by this issue, only users of
    the C API function `wasmtime_trap_code` are affected. (CVE-2022-39394)

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