Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Buffer Overflow: Multiple buffer overflows in DNS and HTTP parsing due to missing bounds checks on lengths and counts before writes.
Memory Safety: Integer overflows and unsafe memcpy in HTTP parsers can lead to buffer overflows and memory corruption.
TLS Certificate Validation Bypass: Certificate validation could be bypassed by failing open on CA load errors or by improper hostname verification (CN fallback).
