CVE-2026-42327 rust-openssl: undefined behavior in X509Ref::ocsp_responders for certificates with non-UTF-8 OCSP URLs

rust-openssl provides OpenSSL bindings for the Rust programming language. From 0.9.7 to before 0.10.79, X509Ref::ocspresponders returns OCSP responder URLs from a certificate's AIA extension as OpensslString, whose Deref wraps the raw bytes with str::fromutf8unchecked. OpenSSL does not enforce th...
