Description:
Three vulnerabilities have been reported in Cisco IOS XR, which can be exploited by malicious people to cause a DoS (Denial of Service).
All three vulnerabilities are caused due to unspecified errors within the processing of MPLS (Multi Protocol Label Switching) packets. This can be exploited via specially crafted MPLS packets to restart the NetIO process, which causes a Modular Services Card on a Cisco Carrier Routing System 1 (CRS-1) or a Line Card on a Cisco 12000 series router to reload.
Successful exploitation requires that MPLS has been configured on the network device.
