Description: An Improper Validation of Consistency within Input issue in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated network-based attacker sending a specifically malformed BGP packet to cause rpd to crash and restart, resulting in a Denial of Service (DoS). This issue only affects systems with BGP traceoptions enabled and requires a BGP session to be already established. Both iBGP and eBGP, and IPv4 and IPv6 are affected by this issue.
