Lifecycle Timeline
4DescriptionCVE.org
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.

Technical ContextAI
A NULL pointer dereference occurs when the application attempts to use a pointer that has not been initialized or has been set to NULL.
RemediationAI
Add NULL checks before pointer dereference operations. Use static analysis to identify potential NULL pointer issues. Enable compiler warnings.
