Doc Type: If docs needed, set a value
Doc Text:
A flaw was found in gRPC. Lack of error handling in the TCP server in Google's gRPC, starting in version 1.23 on POSIX-compatible platforms (for example, 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.
