Technical description

A NULL Pointer Dereference vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, network-based attacker to cause impact to the availability of the device.

When static route points to a reject next hop and a gNMI query is processed for that static route, rpd crashes and restarts.

Junos OS:  * all versions before 21.2R3-S9,

* 21.4 versions before 21.4R3-S10, 

* 22.2 versions before 22.2R3-S6,
