A Missing Release of Memory after Effective Lifetime vulnerability in the routing process daemon (rpd) ofย 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:ย
user@host> show system memory or show system monitor memory status
This issue affects:
Junos OS:ย * All versions before 21.2R3-S8,
from 21.4 before 21.4R3-S8,
