Published: 2024-04-12
| Description: |
An Improper Handling of Exceptional Conditions vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a network-based, unauthenticated attacker to send a specific routing update, causing an rpd core due to memory corruption, leading to a Denial of Service (DoS).

* from 21.2 before 21.2R3-S8,
* from 21.3 before 21.3R3,

* from 22.1 before 22.1R2;
Junos OS Evolved:
* all versions before 21.2R3-S8-EVO,
