Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Denial of Service: An infinite loop can be triggered during early configuration acceptance (LazyConfigAcceptor) if a client sends an immediate EOF. This results in 100% CPU exhaustion and denies service to all other concurrent connections.
Denial of Service: Flawed packet processing state machines can spin indefinitely upon receiving sudden TLS alerts from the peer instead of bubbling up a connection error. This stalls the async reactor.
Memory Corruption: Improperly managed raw context pointers on successful MidHandshake completion can result in use-after-free or invalid pointer dereferences, compromising memory safety.
