Description An issue exists in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved that can lead to a Denial-of-Service (DoS). A local, authenticated attacker with low privileges can trigger this by executing the command 'show route < ( receive-protocol | advertising-protocol ) bgp > detail' when at least one route in the output has specific attributes, causing the rpd process to crash and restart. The 'show route ... extensive' command is not affected.
