Junos OS and Junos OS Evolved: The rpd will crash upon receiving a malformed BGP UPDATE message

An Improper Validation of Syntactic Correctness of Input vulnerability in Routing Protocol Daemon (rpd) Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, network based attacker to cause a Denial of Service (DoS).

When a malformed BGP UPDATE packet is received over an established BGP session, the rpd crashes and restarts.

This issue affects both eBGP and iBGP implementations.
