> Use-After-Free in `Md::fetch` and `Cipher::fetch` | Details | | | ------------------- | ---------------------------------------------- | | Package | `openssl` | | Version | `0.10.70` | | URL | [https://github.com/sfackler/rust-openssl/pull/2390](https://github.com/sfackler/rust-openssl/pull/2390) | | Date | 2025-04-04 | | Patched versions | `>=0.10.72` | | Unaffected versions | `<0.10.39` | 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.
