wasmtime_trap_code C API function has out of bounds write vulnerability

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.

Wasmtime 缓冲区错误漏洞

Wasmtime是一个字节码联盟项目，它是一个独立的仅用于 WebAssembly 和 WASI 的 wasm 优化运行时。 Wasmtime 2.0.2之前的版本存在缓冲区错误漏洞，该漏洞源于其wasmtime_trap_code C API函数存在越界写入。
