Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Buffer Overflow: Three separate fixes address buffer overflows in DER encoding, indicating a persistent lack of bounds checking in this critical signing path.
Authentication Bypass: Multiple critical fixes show certificate validation was initially a no-op (returned True) and later lacked CRL and signature checks, allowing forged or revoked certificates.
Auth Bypass: Missing onboarding state check allowed unauthorized signing and attestation; also a buffer overflow in path copying.
