Description
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to expired pointer dereference error in Routing Protocol Daemon (rpd). A remote non-authenticated attacker can 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.
