Comment 3 Przemyslaw Roguski 2020-11-13 15:20:08 UTC

Statement:

This vulnerability is related to the Node.js grpc package (grpc-node and a new version of it @grpc/grpc-js). OpenShift Container Platform (OCP) delivers the grpc package but it is the C based gRPC version which contains source code for gRPC libraries, therefore not affected by this vulnerability.

Comment 6 Tomas Hoger 2021-01-04 15:27:20 UTC

The grpc packages in Fedora are for the grpc code from the main repo https://github.com/grpc/grpc and they do not contain code from grpc-node from https://github.com/grpc/grpc-node that is affected by this issue.  The grpc-node does not seem to be packaged in Fedora at this time.
