A denial of service vulnerability in Juniper Networks NorthStar Controller Application prior to version 2.1.0 Service Pack 1 may allow an unauthenticated local user to create a fork bomb scenario also known as a rabbit virus or wabbit which will create processes that replicate themselves until all resources are consumed on the system leading to a denial of service to the entire system until it is restarted. Continued attacks by an unauthenticated local user can lead to persistent denials of services.
