Title
Junos OS and Junos OS Evolved: When a static route points to a reject next-hop and a gNMI query for this route is processed, RPD crashes
Summary
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. This issue affects: Junos OS:  * all versions before 21.2R3-S9, * 21.4 versions before 21.4R3-S10,  * 22.2 versions before 22.2R3-S6, * 22.4 versions before 22.4R3-S6, * 23.2 versions before 23.2R2-S3, * 23.4 versions before 23.4R2-S4, * 24.2 versions before 24.2R1-S2, 24.2R2; Junos OS Evolved: * all versions before 22.4R3-S7-EVO, * 23.2-EVO versions before 23.2R2-S3-EVO, * 23.4-EVO versions before 23.4R2-S4-EVO, * 24.2-EVO versions before 24.2R2-EVO.
