Recurring patterns

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

Signature Verification Bypass: Multiple fixes target DNSSEC RRSIG validation, indicating a fragile validation logic prone to bypass via malformed keys or incorrect label counts.

Authentication Bypass: TSIG authentication bypass due to insufficient key/algorithm matching during verification, a critical integrity check.

Signature Verification Bypass: TSIG validation order flaw allowed signature bypass by prioritizing timestamp checks over MAC verification.
