The vulnerability is due to incorrect handling of image list parameters. An attacker could exploit this vulnerability by sending crafted Smart Install packets to TCP port 4786. A successful exploit could cause a Cisco Catalyst switch to reload, resulting in a DoS condition. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability other than disabling Smart Install functionality on the vulnerable device.
