Description The issue is related to an Improper Input Validation vulnerability in the routing protocol daemon (rpd) of Juniper Networks, which can be exploited by an attacker to cause a Denial of Service (DoS) condition. This can occur when the device receives and processes a specific malformed ISO VPN BGP UPDATE packet. Continued receipt of this packet will cause a sustained Denial of Service condition.
