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.

This issue affects:
