Official Description
Check Point Zone Labs ZoneAlarm Internet Security Suite 6.5.722.000, 6.1.737.000, and possibly other versions do not properly validate RegSaveKey, RegRestoreKey, and RegDeleteKey function calls, which allows local users to cause a denial of service (system crash) via a certain combination of these function calls with an HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VETFDDNT\Enum argument.
Technical Analysis
CVE-2006-3540 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
