Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Buffer Overflow: Nine historical buffer overflows, mostly in message pack/unpack, from missing or off-by-one bounds checks on attacker-controlled lengths and offsets.
Auth Bypass: Three authentication bypasses in DNSSEC/TSIG verification, caused by missing RRset validity checks, incorrect signature data computation, and buffer disposal before verification.
Signature Verification Bypass: Three signature verification bypasses: TSIG time check before HMAC, stale MAC in multi-message transfers, and missing canonicalization for certain RR types.
