Description

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.

Affected configurations

• grpc grpc (>= 1.23.0 < 1.53.2) • grpc grpc (>= 1.54.0 < 1.54.3) • grpc grpc (>= 1.55.0 < 1.55.3) • grpc grpc 1.56.0
