GHSA-4fcv-w3qc-ppgg
rust-openssl Use-After-Free in `Md::fetch` and `Cipher::fetch`
When a Some(...) value was passed to the properties argument of either of these functions, a use-after-free would result.
In practice this would nearly always result in OpenSSL treating the properties as an empty string (due to CString::drop's behavior).
