Summary
An Uncontrolled Resource Consumption vulnerability 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.
