+# 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).
+
+The maintainers thank [quitbug](https://github.com/quitbug/) for reporting this vulnerability to us.
