Descriptions
In ZeroMQ before version 4.3.3, there is a denial-of-service vulnerability. Users with TCP transport public endpoints, even with CURVE/ZAP enabled, are impacted. 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. This is patched in version 4.3.3.
En ZeroMQ versiones anteriores a 4.3.3, se presenta una vulnerabilidad de denegación de servicio. Los usuarios con endpoints públicos de transporte TCP, incluso con CURVE/ZAP habilitado, están afectados. Si es abierto un socket TCP sin procesar y es conectado a un endpoint que está completamente configurado con CURVE/ZAP, los clientes legítimos no podrán ser capaces de intercambiar ningún mensaje. Los Protocolos de Enlace se completan correctamente y los mensajes son enviados a la biblioteca, pero la aplicación del servidor nunca los recibe. Esto está parcheado en la versión 4.3.3
