What is CVE-2012-4662?

The DCERPC inspection engine on Cisco Adaptive Security Appliances (ASA) 5500 series and ASA Services Module (ASASM) in Catalyst 6500 series has a vulnerability that permits remote attackers to trigger a denial of service through specially crafted DCERPC packets. This could lead to a reload of the affected devices, disrupting network services and potentially exposing networks to further attacks. Versions before 8.3(2.25), 8.4(2.5), 8.5(1.13) on ASA devices and versions before 4.1(7) on FWSM in Catalyst switches are specifically impacted.
