Description
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).
The maintainers thank quitbug for reporting this vulnerability to us.
