QID 997086: Rust (Rust) Security Update for wasmtime (GHSA-h84q-m8rr-3v9q)

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.

Successful exploitation of this vulnerability could lead to a security breach or could affect integrity, availability, and confidentiality.
