Severity ?
5.3 (Medium) - CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
A Reachable Assertion vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an adjacent, unauthenticated attacker to cause a Denial of Service (DoS).On all Junos OS and Junos OS Evolved devices, when route validation is enabled, a rare condition during BGP initial session establishment can lead to an rpd crash and restart. This occurs specifically when the connection request fails during error-handling scenario. Continued session establishment failures leads to a sustained DoS condition.  This issue affects Junos OS: * All versions before 22.2R3-S6, * from 22.4 before 22.4R3-S6, * from 23.2 before 23.2R2-S3, * from 23.4 before 23.4R2-S4, * from 24.2 before 24.2R2; Junos OS Evolved: * All versions before 22.2R3-S6-EVO, * from 22.4 before 22.4R3-S6-EVO, * from 23.2 before 23.2R2-S3-EVO, * from 23.4 before 23.4R2-S4-EVO, * from 24.2 before 24.2R2-EVO.

En todos los dispositivos Junos OS y Junos OS Evolved, cuando la validaci\u00f3n de ruta est\u00e1 habilitada, una condici\u00f3n poco com\u00fan durante el establecimiento de la sesi\u00f3n inicial de BGP puede provocar un bloqueo y reinicio del rpd. Esto ocurre espec\u00edficamente cuando la solicitud de conexi\u00f3n falla durante un escenario de manejo de errores. Los fallos continuos en el establecimiento de la sesi\u00f3n conducen a una condici\u00f3n de DoS sostenida. Este problema afecta a Junos OS: * Todas las versiones anteriores a 22.2R3-S6, * desde 22.4 hasta 22.4R3-S6, * desde 23.2 hasta 23.2R2-S3, * desde 23.4 hasta 23.4R2-S4, * desde 24.2 hasta 24.2R2; Junos OS Evolved: * Todas las versiones anteriores a 22.2R3-S6-EVO, * desde 22.4 hasta 22.4R3-S6-EVO, * desde 23.2 hasta 23.2R2-S3-EVO, * desde 23.4 hasta 23.4R2-S4-EVO, * desde 24.2 hasta 24.2R2-EVO."
