Highlights
Auth Bypass: 78 prior fixes. Scrutinize any change in this area.

110 high-severity fixes in this history; regressions here are high-impact.
Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Bypasses in OCSP signing certificate verification allow forged or delegated responder certificates from unrelated CAs to validate successfully, bypassing revocation checks.
Side-Channel Attack: Non-constant-time CBC padding checks and MAC computations expose the TLS implementation to timing side-channels and padding oracle attacks like Lucky13.
Memory Safety: Holding references rather than copying keys and private scalar components in cryptographic operations leads to serious use-after-free vulnerabilities.
