Synopsis

The remote device is missing a vendor-supplied security patch.

Description

According to its self-reported version number and configuration, the remote Cisco IOS device is affected by multiple denial of service vulnerabilities :

 - A denial of service vulnerability exists due to improper validation of packets encapsulated in a PIM register message. An unauthenticated, remote attacker can exploit this, by sending an IPv6 PIM register packet to a PIM rendezvous point (RP), to cause the device to restart.
 (CVE-2016-6382)

 - A denial of service vulnerability exists in the IPv4 Multicast Source Discovery Protocol (MSDP) implementation due to improper validation of Source-Active (SA) messages received from a configured MSDP peer. An unauthenticated, remote attacker can exploit this to cause the device to restart.
 (CVE-2016-6392)
