Affected: nats-io nats-server, Red Hat Multicluster Global Hub 1.4.5, Red Hat Multicluster Global Hub 1.6.5, Red Hat multicluster global hub 1.5.3, Red Hat OpenShift Container Platform 4

NATS-Server is a High-Performance server for NATS.io, a cloud and edge native messaging system. Prior to versions 2.11.15 and 2.12.6, a client which can connect to the leafnode port can crash the nats-server with a certain malformed message pre-authentication. Versions 2.11.15 and 2.12.6 contain a fix. As a workaround, disable leafnode support if not needed or restrict network connections to the leafnode port, if plausible without compromising the service offered.
