Upgrade wolfssl/wolfssl to version 5.91 or higher.

Overview

Affected versions of this package are vulnerable to Reusing a Nonce, Key Pair in Encryption in the wc_AriaEncrypt process when ARIA-GCM cipher suites are used in TLS 1.2 or DTLS 1.2 sessions with the MagicCrypto SDK, due to the reuse of an identical 12-byte GCM nonce for every application-data record. An attacker can compromise the confidentiality and integrity of encrypted communications by exploiting predictable nonce reuse to perform cryptographic attacks. This is only exploitable if the build is configured with --enable-aria and the proprietary MagicCrypto SDK (a non-default, opt-in configuration required for Korean regulatory deployments).
