Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Cryptographic Weakness: Skipping block processing for empty associated data enabled cross-nonce forgery of ciphertext tags, and a separate counter carry bug caused keystream repetition every 256 blocks.

Auth Bypass: Exceptions were swallowed during CRL certificate validation, and attribute certificate path signatures were not validated.

Side-Channel Attack: Hardening was required during BIKE KEM decapsulation to prevent timing and decryption-failure oracle attacks.
