| Description | CoreWCF is a port of the service side of Windows Communication Foundation (WCF) to .NET Core. Prior to 1.8.1 and 1.9.1, an unauthenticated remote attacker that can reach a NetTcpBinding, NetNamedPipeBinding, or UnixDomainSocketBinding endpoint can trigger premature EOF handling in the CoreWCF net.tcp, net.pipe, or net.uds framing handshake and pin one server thread-pool worker at full CPU per connection. This issue is fixed in versions 1.8.1 and 1.9.1. | |
