Description Pedro Sampaio 2020-06-04 21:38:30 UTC
Envoy through 1.14.1 is susceptible to increased memory usage in the case where an HTTP/2 client requests a large payload but does not send enough window updates to consume the entire stream and does not reset the stream. The attacker can cause data associated with many streams to be buffered forever.
