Multiple vulnerabilities were found in the Distance Vector Multicast Routing Protocol (DVMRP) feature of Cisco IOS XR Software. The vulnerabilities are caused due to insufficient queue management for Internet Group Management Protocol (IGMP) packets. An unauthenticated remote attacker can exploit these vulnerabilities by sending crafted IGMP traffic to an affected device. Successful exploitation can enable an attacker to cause memory exhaustion, resulting in instability of other processes.
