An Improper Handling of Exceptional Conditions vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a logically adjacent downstream RSVP neighbor to cause kernel memory exhaustion, leading to a kernel crash, resulting in a Denial of Service (DoS).
The kernel memory leak and eventual crash will be seen when the downstream RSVP neighbor has a persistent error which will not be corrected.
System kernel memory can be monitored through the use of the 'show system kernel memory' command as shown below:
user@router> show system kernel memory
Real memory total/reserved: 4130268/ 133344 Kbytes
kmem map free: 18014398509110220 Kbytes
This issue affects:
Junos OS:
* All versions before 20.4R3-S9,
* All versions of 21.2,
* from 21.4 before 21.4R3-S5,
* from 22.1 before 22.1R3-S5,
* from 22.2 before 22.2R3-S3,
* from 22.3 before 22.3R3-S2,
* from 22.4 before 22.4R3,
* from 23.2 before 23.2R2;
Junos OS Evolved:
* All versions before 21.4R3-S5-EVO,
* from 22.1-EVO before 22.1R3-S5-EVO,
* from 22.2-EVO before 22.2R3-S3-EVO,
* from 22.3-EVO before 22.3R3-S2-EVO,
* from 22.4-EVO before 22.4R3-EVO,
