Description An Uncontrolled Resource Consumption issue in the aftmand process of Juniper Networks Junos OS Evolved allows an unauthenticated, network-based attacker to consume memory resources, resulting in a Denial of Service (DoS) condition. The processes do not recover on their own and must be manually restarted. This issue affects both IPv4 and IPv6. Changes in memory usage can be monitored using the CLI command: show system memory node <fpc slot> | grep evo-aftmann.
