How to fix?

Upgrade grcpio to version 1.53.2, 1.54.3, 1.55.3, 1.56.2 or higher.


grcpio is a remote procedure call (RPC) framework.

Affected versions of this package are vulnerable to Uncaught Exception due to the lack of error handling in the TCP server. An attacker can cause a denial of service by initiating a significant number of connections with the server.


This is only exploitable if the server is running on posix-compatible platforms such as Linux.
