Description
An Expired Pointer Dereference vulnerability in Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause Denial of Service (DoS).On all Junos OS and Junos OS Evolved platforms, when an MPLS Label-Switched Path (LSP) is configured with node-link-protection and transport-class, and an LSP flaps, rpd crashes and restarts. Continuous flapping of LSP can cause a sustained Denial of Service (DoS) condition.
This issue affects:
Junos OS:
* All versions before 22.2R3-S4,
* 22.4 versions before 22.4R3-S2,
* 23.2 versions before 23.2R2,
* 23.4 versions before 23.4R2.
Junos OS Evolved:
* All versions before 22.2R3-S4-EVO,
* 22.4-EVO versions before 22.4R3-S2-EVO,
* 23.2-EVO versions before 23.2R2-EVO,
* 23.4-EVO versions before 23.4R2-EVO.
