Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Denial of Service: Both framing versions lacked a maximum frame length limit, allowing a malicious peer to declare an arbitrarily large payload_length and exhaust server memory during buffer allocation.
Denial of Service: Non-fixed-length frames accumulated data in @data without a size cap, enabling memory exhaustion over time from a stream of oversized frames.
