Descriptions

An Improper Validation of Syntactic Correctness of Input vulnerability in Routing Protocol Daemon (rpd) Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, network based attacker to cause a Denial of Service (DoS).

When a malformed BGP UPDATE packet is received over an established BGP session, the rpd crashes and restarts.

This issue affects both eBGP and iBGP implementations.

This issue affects:

Juniper Networks Junos OS



* 21.4 versions prior to 21.4R3-S4;
* 22.1 versions prior to 22.1R3-S3;
* 22.2 versions prior to 22.2R3-S2;
* 22.3 versions prior to 22.3R2-S2, 22.3R3;
* 22.4 versions prior to 22.4R2-S1, 22.4R3;
* 23.2 versions prior to 23.2R1, 23.2R2;




Juniper Networks Junos OS Evolved



* 21.4 versions prior to 21.4R3-S5-EVO;
* 22.1 versions prior to 22.1R3-S3-EVO;
* 22.2 versions prior to 22.2R3-S3-EVO;
* 22.3 versions prior to 22.3R2-S2-EVO;
* 22.4 versions prior to 22.4R3-EVO;
* 23.2 versions prior to 23.2R2-EVO;

Una validación inadecuada de la corrección sintáctica de la vulnerabilidad de entrada en Routing Protocol Daemon (rpd) Juniper Networks Junos OS y Junos OS Evolved permite que un atacante basado en red no autenticado provoque una Denegación de Servicio (DoS). Cuando se recibe un paquete de ACTUALIZACIÓN de BGP con formato incorrecto a través de una sesión BGP establecida, el rpd falla y se reinicia. Este problema afecta tanto a las implementaciones de eBGP como de iBGP. Este problema afecta a: Juniper Networks Junos OS * versiones 21.4 anteriores a 21.4R3-S4; * Versiones 22.1 anteriores a 22.1R3-S3; * Versiones 22.2 anteriores a 22.2R3-S2; * Versiones 22.3 anteriores a 22.3R2-S2, 22.3R3; * Versiones 22.4 anteriores a 22.4R2-S1, 22.4R3; * Versiones 23.2 anteriores a 23.2R1, 23.2R2; Juniper Networks Junos OS Evolved * Versiones 21.4 anteriores a 21.4R3-S5-EVO; * Versiones 22.1 anteriores a 22.1R3-S3-EVO; * Versiones 22.2 anteriores a 22.2R3-S3-EVO; * Versiones 22.3 anteriores a 22.3R2-S2-EVO; * Versiones 22.4 anteriores a 22.4R3-EVO; * Versiones 23.2 anteriores a 23.2R2-EVO;
