Descriptions
On BIG-IP 14.1.0-14.1.2.3, undisclosed requests can lead to a denial of service (DoS) when sent to BIG-IP HTTP/2 virtual servers. The problem can occur when ciphers, which have been blacklisted by the HTTP/2 RFC, are used on backend servers. This is a data-plane issue. There is no control-plane exposure.
En BIG-IP versiones 14.1.0 hasta 14.1.2.3, las peticiones no reveladas pueden conllevar a una denegación de servicio (DoS) cuando son enviadas hacia los servidores virtuales HTTP/2 de BIG-IP. El problema puede ocurrir cuando los cifrados, que han sido puestos en una lista negra por el RFC HTTP/2, son usados en los servidores de backend. Este es un problema del plano de datos. No hay una exposición del plano de control.
