Descriptions

An Improper Input Validation vulnerability in ingress TCP segment processing of Juniper Networks Junos OS Evolved allows a network-based unauthenticated attacker to send a crafted TCP segment to the device, triggering a kernel panic, leading to a Denial of Service (DoS) condition. Continued receipt and processing of this TCP segment could create a sustained Denial of Service (DoS) condition. This issue affects Juniper Networks Junos OS Evolved: 21.3 versions prior to 21.3R3-EVO; 21.4 versions prior to 21.4R2-EVO; 22.1 versions prior to 22.1R2-EVO. This issue does not affect Juniper Networks Junos OS Evolved versions prior to 21.3R1-EVO.

Una vulnerabilidad de Comprobación de Entrada Inapropiada en el procesamiento de segmentos TCP de entrada de Juniper Networks Junos OS Evolved permite a un atacante no autenticado basado en la red enviar un segmento TCP diseñado al dispositivo, desencadenando un pánico del núcleo, conllevando a una condición de Denegación de Servicio (DoS). La recepción y el procesamiento continuados de este segmento TCP podrían crear una condición de Denegación de Servicio (DoS) sostenida. Este problema afecta a Juniper Networks Junos OS Evolved: versiones 21.3 anteriores a 21.3R3-EVO; versiones 21.4 anteriores a 21.4R2-EVO; versiones 22.1 anteriores a 22.1R2-EVO.
