rust-openssl: rustMdCtxRef::digest_final() writes past caller buffer with no length check
Details
`EVP_DigestFinal()` always writes `EVP_MD_CTX_size(ctx)` to the `out` buffer. If `out` is smaller than that, `MdCtxRef::digest_final()` writes past its end, usually corrupting the stack. This is reachable from safe Rust.
