A NULL Pointer Dereference vulnerability in the routing protocol daemon (RPD) of Juniper Networks Junos OS and Junos OS Evolved allows a configured peer sending a BGP UPDATE to cause a denial of service when an import policy with then source-based-forwarding next-hop next-table <X> is configured to reference a routing table that does not exist.
Weakness
The product dereferences a pointer that it expects to be valid but is NULL.
