GHSA-p25m-jpj4-qcrr Denial of Service Vulnerability in gRPC TCP Server (Posix-compatible platforms)

• RubyGems grpc: >= 1.56.0, < 1.56.2 → fixed in 1.56.2 • RubyGems grpc: >= 1.55.0, < 1.55.3 → fixed in 1.55.3 • RubyGems grpc: >= 1.54.0, < 1.54.3 → fixed in 1.54.3 • RubyGems grpc: >= 1.53.0, < 1.53.2 → fixed in 1.53.2 • PyPI grpcio: >= 1.55.0, < 1.55.3 → fixed in 1.55.3 • PyPI grpcio: >= 1.54.0, < 1.54.3 → fixed in 1.54.3 • PyPI grpcio: >= 1.53.0, < 1.53.2 → fixed in 1.53.2

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.
