Description
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to access of uninitialized pointer error in the Routing Protocol Daemon (rpd). A remote non-authenticated attacker can cause a Denial of Service (DoS).
When an MPLS ping is performed on BGP LSPs, the RPD might crash.
Repeated execution of this operation will lead to a sustained DoS.
Mitigation
Install updates from vendor's website.
