CVE-2024-2758

CVE-2024-2758 concerns Tempesta FW. The vulnerability stems from how HTTP/2 CONTINUATION frames are handled when rate limits are not enabled by default, enabling potential denial-of-service via excessive CONTINUATION traffic (OOM/CPU exhaustion depending on implementation). The initial descriptio...

RUSTSEC-2024-0332 Degradation of service in h2 servers 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...
