Http4s is a Scala interface for HTTP services. Prior to 0.23.35 and 1.0.0-M47, Ember\u2019s HTTP\/2 flow-control window is replenished according to bytes received from the network rather than bytes consumed by the application, while each stream stores DATA in an unbounded channel. A hostile peer can therefore send a body faster than a slow or non-draining application consumes it, retaining payloads in heap on an ember-server or ember-client configured with withHttp2. The patch bounds the per-stream H2Connection body channel so application consumption applies backpressure. This issue is fixed in versions 0.23.35 and 1.0.0-M47.<\/p>\n","protected":false},"excerpt":{"rendered":"
