Microsoft Windows XP and Windows Server 2003 do not properly handle user logoff, which might allow local users to gain the privileges of a previous system user, possibly related to user profile unload failure. NOTE: it is not clear whether this is an issue in Windows itself, or an interaction with another product. The issue might involve ZoneAlarm not being able to terminate processes when it cannot prompt the user.

vsdatant.sys in Check Point Zone Labs ZoneAlarm Pro before 7.0.302.000 does not validate certain arguments before being passed to hooked SSDT function handlers, which allows local users to cause a denial of service (system crash) or possibly execute arbitrary code via crafted arguments to the (1) NtCreateKey and (2) NtDeleteFile functions.

ZoneAlarm Pro 6.5.737.000, 6.1.744.001, and possibly earlier versions and other products, allows local users to cause a denial of service (system crash) by sending malformed data to the vsdatant device driver, which causes an invalid memory access.

ZoneAlarm Pro 7.0.362.000 does not properly validate certain parameters to System Service Descriptor Table (SSDT) function handlers, which allows local users to cause a denial of service (crash) and possibly gain privileges via the (1) NtCreatePort and (2) NtDeleteFile kernel SSDT hooks, a partial regression of CVE-2007-2083.

ZoneAlarm 2.1 through 2.6 and ZoneAlarm Pro 2.4 and 2.6 allows local users to bypass filtering via non-standard TCP packets created with non-Windows protocol adapters.

ZoneAlarm Pro 3.0 and 3.1, when configured to block all traffic, allows remote attackers to cause a denial of service (CPU and memory consumption) via a large number of SYN packets (SYN flood). NOTE: the vendor was not able to reproduce the issue.

ZoneAlarm Pro 3.0 MailSafe allows remote attackers to bypass filtering and possibly execute arbitrary code via email attachments containing a trailing dot after the file extension.

The DeviceIoControl function in the TrueVector Device Driver (VSDATANT) in ZoneAlarm before 3.7.211, Pro before 4.0.146.029, and Plus before 4.0.146.029 allows local users to gain privileges via certain signals (aka "Device Driver Attack").

Stack-based buffer overflow in the SMTP service support in vsmon.exe in Zone Labs ZoneAlarm before 4.5.538.001, ZoneLabs Integrity client 4.0 before 4.0.146.046, and 4.5 before 4.5.085, allows remote attackers to execute arbitrary code via a long RCPT TO argument.

The Mobile Code filter in ZoneAlarm Pro 5.0.590.015 does not filter mobile code within an SSL encrypted session, which could allow remote attackers to bypass the mobile code filtering. NOTE: it has been disputed by the vendor that this behavior is required by the SSL specification.

Zone Labs IMsecure and IMsecure Pro before 1.5 allow remote attackers to bypass Active Link Filtering via an instant message containing a URL with hex encoded file extensions.

ZoneAlarm sends sensitive system and network information in cleartext to the Zone Labs server if a user requests more information about an event.

ZoneAlarm Pro 4.5.538.001 and possibly other versions allows remote attackers to bypass e-mail protection via attachments whose names contain certain non-English characters.

Zone Alarm Pro 1.0 through 5.1 gives full access to %windir%\Internet Logs\* to the EVERYONE group, which allows local users to cause a denial of service by modifying the folder contents or permissions. NOTE: this issue has been disputed by the vendor, who claims that it does not affect product functionality since the same information is also saved in a protected file

vsdatant.sys in Zone Lab ZoneAlarm before 5.5.062.011, ZoneAlarm Wireless before 5.5.080.000, Check Point Integrity Client 4.x before 4.5.122.000 and 5.x before 5.1.556.166 do not properly verify that the ServerPortName argument to the NtConnectPort function is a valid memory address, which allows local users to cause a denial of service (system crash) when ZoneAlarm attempts to dereference an invalid pointer.

Integer overflow in Computer Associates Vet Antivirus library, as used by CA InoculateIT 6.0, eTrust Antivirus r6.0 through 7.1, eTrust Antivirus for the Gateway r7.0 and r7.1, eTrust Secure Content Manager, eTrust Intrusion Detection, BrightStor ARCserve Backup (BAB) r11.1, Vet Antivirus, Zonelabs ZoneAlarm Security Suite, and ZoneAlarm Antivirus, allows remote attackers to gain privileges via a compressed VBA directory with a project name length of -1, which leads to a heap-based buffer overflow.

Zone Labs (1) ZoneAlarm Pro 6.0, (2) ZoneAlarm Internet Security Suite 6.0, (3) ZoneAlarm Anti-Virus 6.0, (4) ZoneAlarm Anti-Spyware 6.0 through 6.1, and (5) ZoneAlarm 6.0 allow remote attackers to bypass the "Advanced Program Control and OS Firewall filters" setting via URLs in "HTML Modal Dialogs" (window.location.href) contained within JavaScript tags.

Untrusted search path vulnerability in the TrueVector service (VSMON.exe) in Zone Labs ZoneAlarm 6.x and Integrity does not search ZoneAlarm's own folders before other folders that are specified in a user's PATH, which might allow local users to execute code as SYSTEM by placing malicious DLLs into a folder that has insecure permissions, but is searched before ZoneAlarm's folder. NOTE: since this issue is dependent on the existence of a vulnerability in a separate product (weak permissions of executables or libraries, or the execution of malicious code), perhaps it should not be included in CVE.

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.

ZoneAlarm and ZoneAlarm Pro before 5.5.062, with ad-blocking enabled, allows remote web sites to cause a denial of service (application instability or system hang) via certain JavaScript.
