Descriptions

In Eclipse Vert.x version 4.3.0 to 4.5.9, the gRPC server does not limit the maximum length of message payload (Maven GAV: io.vertx:vertx-grpc-server and io.vertx:vertx-grpc-client). This is fixed in the 4.5.10 version. Note this does not affect the Vert.x gRPC server based grpc-java and Netty libraries (Maven GAV: io.vertx:vertx-grpc)

A flaw was found in the gRPC server in Eclipse Vert.x, which does not limit the maximum length of the message payload. This may lead to excessive memory consumption in a server or a client, causing a denial of service.

Release of OpenShift Serverless Logic 1.34.0. Issues addressed include a code execution vulnerability.
