Descriptions
An Improper Check for Unusual or Exceptional Conditions vulnerability in the Packet Forwarding Engine (pfe) of Juniper Networks Junos OS on MX Series allows a unauthenticated network-based attacker to cause an infinite loop, resulting in a Denial of Service (DoS).
An attacker who sends malformed TCP traffic via an interface configured with PPPoE, causes an infinite loop on the respective PFE. This results in consuming all resources and a manual restart is needed to recover.
This issue affects interfaces with PPPoE configured and tcp-mss enabled.
This issue affects Juniper Networks Junos OS
* All versions prior to 20.4R3-S7;
* 21.1 version 21.1R1 and later versions;
* 21.2 versions prior to 21.2R3-S6;
* 21.3 versions prior to 21.3R3-S5;
* 21.4 versions prior to 21.4R3-S3;
* 22.1 versions prior to 22.1R3-S4;
* 22.2 versions prior to 22.2R3;
* 22.3 versions prior to 22.3R2-S2;
* 22.4 versions prior to 22.4R2;
Una verificación inadecuada de la vulnerabilidad de condiciones inusuales o excepcionales en Packet Forwarding Engine (pfe) de Juniper Networks Junos OS en la serie MX permite que un atacante basado en red no autenticado provoque un bucle infinito, lo que resulta en una Denegación de Servicio (DoS). Un atacante que envía tráfico TCP con formato incorrecto a través de una interfaz configurada con PPPoE provoca un bucle infinito en el PFE respectivo. Esto da como resultado el consumo de todos los recursos y es necesario un reinicio manual para recuperarse. Este problema afecta a las interfaces con PPPoE configurado y tcp-mss habilitado. Este problema afecta a Juniper Networks Junos OS * Todas las versiones anteriores a 20.4R3-S7; * 21.1 versión 21.1R1 y versiones posteriores; * Versiones 21.2 anteriores a 21.2R3-S6; * Versiones 21.3 anteriores a 21.3R3-S5; * Versiones 21.4 anteriores a 21.4R3-S3; * Versiones 22.1 anteriores a 22.1R3-S4; * Versiones 22.2 anteriores a 22.2R3; * Versiones 22.3 anteriores a 22.3R2-S2; * Versiones 22.4 anteriores a 22.4R2;
