CVE-2022-22160

An Unchecked Error Condition vulnerability in the subscriber management daemon (smgd) of Juniper Networks Junos OS allows an unauthenticated adjacent attacker to cause a crash of and thereby a Denial of Service (DoS). In a subscriber management / broadband edge environment if a single session group configuration contains dual-stack and a pp0 interface, smgd will crash and restart every time a PPPoE client sends a specific message. This issue affects Juniper Networks Junos OS on MX Series: 16.1 version 16.1R1 and later versions prior to 18.4R3-S10; 19.1 versions prior to 19.1R2-S3, 19.1R3-S7; 19.2 versions prior to 19.2R1-S8, 19.2R3-S4; 19.3 versions prior to 19.3R3-S4; 19.4 versions prior to 19.4R3-S5; 20.1 versions prior to 20.1R3-S3; 20.2 versions prior to 20.2R3-S3; 20.3 versions prior to 20.3R3-S2; 20.4 versions prior to 20.4R3; 21.1 versions prior to 21.1R3; 21.2 versions prior to 21.2R2. This issue does not affect Juniper Networks Junos OS versions prior to 16.1R1.

Una vulnerabilidad de condición de error no comprobada en el demonio de gestión de suscriptores (smgd) del sistema operativo Junos de Juniper Networks permite que un atacante adyacente no autenticado provoque un bloqueo y, por tanto, una denegación de servicio (DoS). En un entorno de gestión de suscriptores/borde de banda ancha, si una configuración de grupo de sesión única contiene dual-stack y una interfaz pp0, smgd se bloqueará y reiniciará cada vez que un cliente PPPoE envíe un mensaje específico. Este problema afecta al sistema operativo Junos de Juniper Networks en la serie MX: 16.1 versión 16.1R1 y versiones posteriores anteriores a 18.4R3-S10; 19.1 versiones anteriores a 19.1R2-S3, 19.1R3-S7; 19.2 versiones anteriores a 19.2R1-S8, 19.2R3-S4; 19.3 versiones anteriores a 19.3R3-S4; 19.4 versiones anteriores a 19. 4R3-S5; 20.1 versiones anteriores a 20.1R3-S3; 20.2 versiones anteriores a 20.2R3-S3; 20.3 versiones anteriores a 20.3R3-S2; 20.4 versiones anteriores a 20.4R3; 21.1 versiones anteriores a 21.1R3; 21.2 versiones anteriores a 21.2R2. Este problema no afecta a las versiones del sistema operativo Junos de Juniper Networks anteriores a la 16.1R1
