Descriptions

A Missing Release of Memory after Effective Lifetime vulnerability in Routing Protocol Daemon (RPD) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause an rpd crash, leading to Denial of Service (DoS).

On all Junos OS and Junos OS Evolved platforms, when traffic engineering is enabled for OSPF or ISIS, and a link flaps, a patroot memory leak is observed. This memory leak, over time, will lead to an rpd crash and restart.

The memory usage can be monitored using the below command.

user@host> show task memory detail | match patroot
This issue affects:

Juniper Networks Junos OS



* All versions earlier than 21.2R3-S3;
* 21.3 versions earlier than 21.3R3-S5;
* 21.4 versions earlier than 21.4R3-S3;

* 22.2 versions earlier than 22.2R3-EVO.

Una vulnerabilidad de liberación de memoria faltante después de la vida útil efectiva en Routing Protocol Daemon (RPD) de Juniper Networks Junos OS y Junos OS Evolved permite que un atacante adyacente no autenticado provoque un bloqueo de rpd, lo que lleva a una denegación de servicio (DoS). En todas las plataformas Junos OS y Junos OS Evolved, cuando la ingeniería de tráfico está habilitada para OSPF o ISIS y un enlace falla, se observa una pérdida de memoria de patroot. Esta pérdida de memoria, con el tiempo, provocará un bloqueo y reinicio del rpd. El uso de la memoria se puede monitorear usando el siguiente comando. user@host> show task memory detail | match patroot Este problema afecta a: Juniper Networks Junos OS * Todas las versiones anteriores a 21.2R3-S3; * Versiones 21.3 anteriores a 21.3R3-S5; * Versiones 21.4 anteriores a 21.4R3-S3; * Versiones 22.1 anteriores a 22.1R3; * Versiones 22.2 anteriores a 22.2R3. Juniper Networks Junos OS Evolved * Todas las versiones anteriores a 21.3R3-S5-EVO; * Versiones 21.4 anteriores a 21.4R3-EVO; * Versiones 22.1 anteriores a 22.1R3-EVO; * Versiones 22.2 anteriores a 22.2R3-EVO.
