Description
Google's oss-fuzz project reports: Denial-of-Service on CURVE/ZAP-protected servers by unauthenticated clients. If a raw TCP socket is opened and connected to an endpoint that is fully configured with CURVE/ZAP, legitimate clients will not be able to exchange any message. Handshakes complete successfully, and messages are delivered to the library, but the server application never receives them.
