Description The issue is related to an improper validation of syntactic correctness of input in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved. This allows a network-based, unauthenticated attacker to cause a Denial of Service (DoS) by sending a BGP update with a specifically malformed TLV over an established BGP session, causing rpd to crash and restart.
