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 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
