Summary:
A vulnerability in the multicast DNS (mDNS) gateway function of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to reload the vulnerable device. The vulnerability is due to improper validation of mDNS packets. An attacker could exploit this vulnerability by sending malformed IP version 4 (IPv4) or IP version 6 (IPv6) packets on UDP port 5353. An exploit could allow the attacker to cause a denial of service (DoS) condition. Cisco has released software updates that address this vulnerability. This advisory is available at the references. Note: The March 25, 2015, Cisco IOS & XE Software Security Advisory bundled publication includes seven Cisco Security Advisories. The advisories address vulnerabilities in Cisco IOS Software and Cisco IOS XE Software. Individual publication links are in Cisco Event Response: Semiannual Cisco IOS & XE Software Security Advisory Bundled Publication at the references.

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
