TITLE

Check Point Zone Labs ZoneAlarm of vsdatant.sys Vulnerability gained in

DESCRIPTION

vsdatant.sys 6.5.737.0 in Check Point Zone Labs ZoneAlarm before 7.0.362 allows local users to gain privileges via a crafted Interrupt Request Packet (Irp) in a METHOD_NEITHER (1) IOCTL 0x8400000F or (2) IOCTL 0x84000013 request, which can be used to overwrite arbitrary memory locations. Multiple Check Point ZoneAlarm products are prone to local privilege-escalation vulnerabilities. An attacker can exploit these issues to gain elevated privileges and completely compromise an affected computer. These issues have been confirmed in: ZoneAlarm 6.5.737 ZoneAlarm Security Suite 5.5.062.004 and 6.5.737. Other versions are likely vulnerable as well. NOTE: This BID is being retired because it is a duplicate of BID 25365 (Check Point Zone Labs Multiple Products Local Privilege Escalation Vulnerabilities). The following are vulnerable: - Versions prior to ZoneAlarm 7.0.362 - Zone Labs products that include 'vsdatant.sys' 6.5.737.0. ZoneAlarm is a personal computer firewall that protects personal data and privacy. There are multiple security vulnerabilities in the implementation and installation of ZoneAlarm, local attackers may use this vulnerability to elevate their own privileges. Since some programs run as system services, attackers can replace the installed ZoneAlarm files with their own code, which will then be executed with system-level privileges. ---------------------------------------------------------------------- BETA test the new Secunia Personal Software Inspector!

SOLUTION: Update to version 7.0.362. 2) Discovered by an anonymous person and reported via iDefense Labs.

BACKGROUND Zone Alarm products provide security solutions such as anti-virus, firewall, spy-ware, and ad-ware protection. The vsdatant.sys driver, also known as the TrueVector Device Driver, is the core firewall driver in ZoneAlarm products. http://www.zonelabs.com/ II. The problems specifically exist within the IOCTL handling code in the vsdatant.sys device driver. The device driver fails to validate user-land supplied addresses passed to IOCTL 0x8400000F and IOCTL 0x84000013. Since the Irp parameters are not correctly validated, an attacker could utilize these IOCTLs to overwrite arbitrary memory with the constant double-word value of 0x60001 or the contents of a buffer returned from ZwQuerySystemInformation. This includes kernel memory as well as the code segments of running processes. III. The access control mechanisms under a default installation allow restricted accounts to access the affected device drivers. IV. V. WORKAROUND Changing the access control mechanisms for the affected device drivers will prevent exploitation by restricted accounts. VI. http://www.zonealarm.com/store/content/catalog/products/trial_zaFamily/trial_zaFamily.jsp VII. CVE INFORMATION The Common Vulnerabilities and Exposures (CVE) project has assigned the name CVE-2007-4216 to this issue. This is a candidate for inclusion in the CVE list (http://cve.mitre.org/), which standardizes names for security problems. VIII.
