Hitachi Energy GMS600 Vulnerable to Bleichenbacher Attack via CVE-2022-4304

Hitachi Energy GMS600 versions 1.3.0 and 1.3.1 are affected by CVE-2022-4304, a vulnerability in the OpenSSL RSA Decryption implementation; an attacker could exploit this timing-based side channel to recover plaintext across a network in a Bleichenbacher-style attack by sending trial messages to the server and recording processing times, eventually decrypting application data.

rust-openssl AES Key Wrap Out-of-Bounds Write Vulnerability

The rust-openssl package is vulnerable to an out-of-bounds write due to an incorrect bounds assertion in the `aes::unwrap_key()` function, potentially leading to arbitrary code execution if attacker-controlled buffer sizes are permitted.

rust-openssl X509Ref::ocsp_responders Undefined Behavior Vulnerability

The `X509Ref::ocsp_responders` function in rust-openssl versions 0.9.7 to 0.10.78 returns OCSP responder URLs from a certificate's AIA extension without proper UTF-8 validation, leading to undefined behavior when processing certificates with non-UTF-8 OCSP URLs.

rust-openssl Stack Buffer Overflow Vulnerability

The rust-openssl crate is vulnerable to a stack-based buffer overflow (CVE-2026-41681) where the `EVP_DigestFinal()` function writes beyond the allocated buffer, potentially corrupting the stack, affecting versions >= 0.10.39 and < 0.10.78.

Heap/Stack Overflow in rust-openssl with OpenSSL 1.1.x

The rust-openssl crate's `Deriver::derive` and `PkeyCtxRef::derive` functions can cause heap/stack overflows when used with OpenSSL 1.1.x due to insufficient buffer length validation in X25519, X448, DH, and HKDF-extract, affecting rust-openssl versions >= 0.9.27 and < 0.10.78.
