A Missing Release of Memory after Effective Lifetime vulnerability in the routing process daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an attacker to send a malformed BGP Path attribute update which allocates memory used to log the bad path attribute. This memory is not properly freed in all circumstances, leading to a Denial of Service (DoS).

Consumed memory can be freed by manually restarting Routing Protocol Daemon (rpd).

Memory utilization could be monitored by: 
user@host> show system memory or show system monitor memory status
