gRPC Swift 1.0.0 ..< 1.7.1: Denial of Service Vulnerability

In gRPC Swift versions 1.0.0 through to 1.7.1 inclusive, gRPC servers were vulnerable to denial of service attacks from a reachable precondition due to incorrect logic when handling GOAWAY frames. This was discovered by automated fuzz testing.

Users must upgrade to 1.7.2 to resolve this issue.
