GHSA-Q6CP-QFWQ-4GCV h2 servers vulnerable to degradation of service with CONTINUATION Flood

An attacker can send a flood of CONTINUATION frames, causing h2 to process them indefinitely. This results in an increase in CPU usage. Tokio task budget helps prevent this from a complete denial-of-service, as the server can still respond to legitimate requests, albeit with increased latency. Mo...
