"value": "An Improper Handling of Exceptional Conditions vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a network-based, unauthenticated attacker to cause Denial of Service (DoS).\n\nWhen a BGP UPDATE with malformed path attribute is received over an established BGP session, rpd crashes and restarts. \n\nContinuous receipt of a BGP UPDATE with a specifically malformed path attribute will create a sustained Denial of Service (DoS) condition for impacted devices.
