CVE-2007-5044
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedZoneAlarm 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceZoneAlarm Pro 7.0.362.000 contains improper parameter validation in kernel SSDT (System Service Descriptor Table) hooks for NtCreatePort and NtDeleteFile functions. This allows local attackers to crash the system (DoS) and potentially elevate privileges by exploiting insufficient validation of arguments passed to these kernel-mode SSDT handlers.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check if ZoneAlarm is installedLook for ZoneAlarm in the list of installed programs via Control Panel > Programs and Features, or check for ZoneAlarm executable files in Program Files directoriesAffected if ZoneAlarm Pro is not installed on the system
-
Verify the exact ZoneAlarm versionOpen ZoneAlarm Pro and navigate to About/Version information, or right-click the ZoneAlarm icon and select About. Confirm the version number is exactly 7.0.362.000Affected if The installed version is ZoneAlarm Pro 7.0.362.000
-
Confirm ZoneAlarm kernel protection is activeOpen ZoneAlarm Pro main interface and check if the firewall/antivirus real-time protection is enabled and running. The SSDT hooks are only active when the kernel-mode protection module is loadedAffected if ZoneAlarm Pro 7.0.362.000 is running with active firewall or real-time protection enabled
-
Check system stability related to ZoneAlarmReview Windows Event Viewer System and Application logs for any kernel-mode driver errors, system crashes, or blue screen events that coincide with ZoneAlarm activity, particularly when applications attempt file operations or port creationAffected if System crashes or kernel errors occur when applications perform operations that trigger NtCreatePort or NtDeleteFile calls while ZoneAlarm is active
You are affected if ZoneAlarm Pro version 7.0.362.000 is installed and running with active kernel protection, as the vulnerability resides in the SSDT hooks that are only engaged during active protection

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade to a current version of ZoneAlarm or the vendor's latest security product, as this vulnerability is a known regression from CVE-2007-2083 and older vulnerable versions should no longer be in production use.
