Lack of error handling in the TCP server in Google’s gRPC starting version
1.23 on posix-compatible platforms (ex. Linux) allows an attacker to cause
a denial of service by initiating a significant number of connections with
the server. Note that gRPC C++ Python, and Ruby are affected, but gRPC
Java, and Go are NOT affected.
