Description:
Some vulnerabilities and a security issue have been reported in ZoneAlarm products, which can be exploited by malicious, local users to gain escalated privileges.

1) Insufficient address space verification within the 0x8400000F and 0x84000013 IOCTL handlers of vsdatant.sys and insecure permissions on the "\\.\vsdatant" device interface can be exploited to e.g. access the said IOCTL handlers and overwrite arbitrary memory and execute code with kernel privileges.

These vulnerabilities are reported in Check Point Zone Labs Zone Alarm Free including vsdatant.sys version 6.5.737.0. Other versions may also be affected.

2) Insecure default Access Control List (ACL) settings when ZoneAlarm tools are installed can be exploited to gain escalated privileges by replacing certain files.

The security issue is reported in ZoneAlarm Security Suite 5.5.062.004 and 6.5.737. Other versions may also be affected.
