HTTP2ToRawGRPCServerCodec in gRPC Swift 1.1.1 and earlier allows remote attackers to deny service via the delivery of many small messages within a single HTTP/2 frame, leading to Uncontrolled Recursion and stack consumption.
The product does not properly control the amount of recursion that takes place, consuming excessive resources, such as allocated memory or the program stack.
