Summary
On Juniper Networks Junos OS and Junos OS Evolved devices, processing a specific UPDATE for an EBGP peer can lead to a routing process daemon (RPD) crash and restart. This issue occurs only when the device is receiving and processing the BGP UPDATE for an EBGP peer. This issue does not occur when the device is receiving and processing the BGP UPDATE for an IBGP peer. However, the offending BGP UPDATE can originally come from an EBGP peer, propagates through the network via IBGP peers without causing crash, then it causes RPD crash when it is processed for a BGP UPDATE towards an EBGP peer. Repeated receipt and processing of the same specific BGP UPDATE can result in an extended Denial of Service (DoS) condition. This issue affects: Juniper Networks Junos OS: 17.3R3-S6, 17.4R2-S7, and 18.1R3-S7. Juniper Networks Junos OS Evolved 19.2R2-EVO and later versions, prior to 19.3R1-EVO. Other Junos OS releases are not affected.

Este problema se produce solo cuando el dispositivo est\u00e1 recibiendo y procesando la BGP UPDATE para un peer EBGP. Este problema no se produce cuando el dispositivo recibe y procesa el BGP UPDATE para un peer IBGP. Sin embargo, el BGP UPDATE ofensivo puede provenir originalmente desde un peer EBGP, se propaga por medio de la red por medio de los peer IBGP sin causar un bloqueo, luego causa un bloqueo de RPD cuando es procesado para un BGP UPDATE hacia un peer EBGP. La recepci\u00f3n y el procesamiento repetido de la misma BGP UPDATE espec\u00edfica pueden resultar en una condici\u00f3n extendida de Denegaci\u00f3n de Servicio (DoS).
