Descriptions

In ZeroMQ libzmq before 4.0.9, 4.1.x before 4.1.7, and 4.2.x before 4.3.2, a remote, unauthenticated client connecting to a libzmq application, running with a socket listening with CURVE encryption/authentication enabled, may cause a stack overflow and overwrite the stack with arbitrary data, due to a buffer overflow in the library. Users running public servers with the above configuration are highly encouraged to upgrade as soon as possible, as there are no known mitigations.

En ZeroMQ libzmq anterior a versión 4.0.9, versiones 4.1.x anteriores a 4.1.7, y versiones 4.2.x anteriores a 4.3.2, un cliente no identificado remoto que se conecta a una aplicación libzmq, ejecutándose con un socket de escucha con el cifrado y autenticación CURVE habilitado, puede causar un desbordamiento de pila y sobreescritura de pila con datos arbitrarios, debido a un desbordamiento de búfer en la biblioteca. Se exhorta a los usuarios que ejecutan servidores públicos con la configuración anterior que realicen su actualización lo antes posible, ya que no existen mitigaciones conocidas.
