What is CVE-2011-4006?

The ESMTP inspection feature in Cisco's Adaptive Security Appliances (ASA) 5500 series can be exploited by remote attackers to induce excessive CPU usage, effectively resulting in a denial of service. This occurs through an unspecified closing sequence that triggers a bug (ID CSCtt32565). Devices running software versions 8.2 through 8.5 are particularly susceptible, making timely updates imperative to maintain security and performance.
