The NTP implementation in Cisco IOS 12.0 through 12.4 and 15.0 through 15.1, and IOS XE 2.1 through 3.3, does not properly handle encapsulation of multicast NTP packets within MSDP SA messages, which allows remote attackers to cause a denial of service (device reload) by leveraging an MSDP peer relationship, aka Bug ID CSCuc81226.

CVE-2013-5472 [HIGH] CWE-399 Cisco IOS Software Multicast Network Time Protocol Denial of Service Vulnerability
Cisco IOS Software Multicast Network Time Protocol Denial of Service Vulnerability
A vulnerability in the implementation of the Network Time Protocol (NTP) feature in Cisco IOS Software could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition.
The vulnerability is due to the improper handling of multicast NTP packets that are sent to an affected device encapsulated in a Multicast Source Discovery Protocol (MSDP) Source-Active (SA) message from a configured MSDP peer. An attacker could exploit this vulnerability by sending multicast NTP packets to an affected device. Repeated exploitation could result in a sustained DoS condition.
Cisco has released software updates that address this vulnerability. A workaroun
