Cisco Security Advisory – Cisco Intrusion Prevention System (IPS) platforms that have gigabit network interfaces installed and are deployed in inline mode contain a denial of service vulnerability in the handling of jumbo Ethernet frames. This vulnerability may lead to a kernel panic that requires a power cycle to recover platform operation. Platforms deployed in promiscuous mode only or that do not contain gigabit network interfaces are not vulnerable.
