Name of the Vulnerable Software and Affected Versions Cisco IOS versions 15.3(3)S and earlier

Description A denial of service issue exists due to chunk corruption when MLDP and a large number of VRFs are configured on a device. An attacker could exploit this by sending a large number of multicast flows over configured VRF instances, leading to a device reload and a denial of service condition. The attacker would likely need access to trusted, internal networks to successfully exploit this issue.
