CVE-2012-1366

Name of the Vulnerable Software and Affected Versions Cisco IOS versions prior to 15.1(1)SY on ASR 1000 devices

Description The issue allows remote attackers to cause a denial of service, resulting in a device reload, via crafted Multicast Listener Discovery (MLD) packets when MLD tracking is enabled for IPv6.

Recommendations For versions prior to 15.1(1)SY, update to version 15.1(1)SY or later to resolve the issue. As a temporary workaround, consider disabling MLD tracking for IPv6 to minimize the risk of exploitation.
