OpenSSL Security Patches Fix Remote Code Execution Risk

**Executive Summary:** This advisory details an emergency OpenSSL maintenance release addressing multiple high-severity vulnerabilities — most notably a PKCS#7/S/MIME use-after-free (CVE-2026-45447) that can be triggered remotely and may lead to remote code execution, an AES-OCB nonce-reuse flaw (CVE-2026-45445) that breaks confidentiality and enables forgery, and several QUIC/OCSP-related denial-of-service and memory corruption issues; administrators are urged to apply patches (e.g., 4.0.1 or supported 1.1.1 updates) and review dependency trees immediately.
