Title:	CiscoIOS XE Software Multicast Routing Denial of Service Vulnerabilities
Summary:	Multiple vulnerabilities in the multicast subsystem of Cisco IOS XE;Software could allow an unauthenticated, remote attacker to create a denial of service (DoS) condition. The;issues are in IPv4 Multicast Source Discovery Protocol (MSDP) and IPv6 Protocol Independent Multicast (PIM).
Description:	Summary: Multiple vulnerabilities in the multicast subsystem of Cisco IOS XE Software could allow an unauthenticated, remote attacker to create a denial of service (DoS) condition. The issues are in IPv4 Multicast Source Discovery Protocol (MSDP) and IPv6 Protocol Independent Multicast (PIM). Vulnerability Insight: The first vulnerability (Cisco bug ID CSCud36767) is due to insufficient checking of MSDP Source-Active (SA) messages received from a configured MSDP peer. An attacker who can send traffic to the IPv4 address of a device could exploit this vulnerability by sending a packet designed to trigger the issue to the affected device. The second vulnerability (Cisco bug ID CSCuy16399) is due to insufficient checking of packets encapsulated in a PIM register message. An attacker who can send a malformed IPv6 PIM register packet to a PIM rendezvous point (RP) could exploit the vulnerability. Vulnerability Impact: A successful exploit could cause the affected device to restart. Solution: See the referenced vendor advisory for a solution. CVSS Score: 7.8 CVSS Vector: AV:N/AC:L/Au:N/C:N/I:N/A:C
