Descriptions
A Race Condition in the 'show chassis pic' command in Juniper Networks Junos OS Evolved may allow an attacker to crash the port interface concentrator daemon (picd) process on the FPC, if the command is executed coincident with other system events outside the attacker's control, leading to a Denial of Service (DoS) condition. Continued execution of the CLI command, under precise conditions, could create a sustained Denial of Service (DoS) condition. This issue affects all Juniper Networks Junos OS Evolved versions prior to 20.1R2-EVO on PTX10003 and PTX10008 platforms. Junos OS is not affected by this vulnerability.
Una condición de carrera en el comando "show chassis pic" en Juniper Networks Junos OS Evolved puede permitir a un atacante bloquear el proceso del demonio concentrador de interfaz de puertos (picd) en el FPC, si el comando se ejecuta coincidiendo con otros eventos del sistema fuera del control del atacante, conllevando a una condición de Denegación de Servicio (DoS). La ejecución continuada del comando CLI, en condiciones precisas, podría crear una condición de Denegación de Servicio (DoS) sostenida. Este problema afecta a todas las versiones de Junos OS Evolved anteriores a 20.1R2-EVO de Juniper Networks en las plataformas PTX10003 y PTX10008. Junos OS no está afectado por esta vulnerabilidad
