CVE-2006-6618
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 · uneditedAntiHook 3.0.0.23 - Desktop relies on the Process Environment Block (PEB) to identify a process, which allows local users to bypass the product's controls on a process by spoofing the (1) ImagePathName, (2) CommandLine, and (3) WindowTitle fields in the PEB.
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 confidenceAntiHook 3.0.0.23 uses the Process Environment Block (PEB) to identify processes for its security controls. Local users can spoof the ImagePathName, CommandLine, and WindowTitle fields in the PEB to bypass these controls.

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.
-
Identify installed security productsOpen Control Panel > Programs and Features (or 'Add or Remove Programs' on older systems) and look for any of these: AVG Antivirus Plus Firewall, Comodo Personal Firewall, Filseclab Personal Firewall, Antihook, Look N Stop, or Symantec Sygate Personal FirewallAffected if Any of these six products are installed on the system
-
Check product versionRight-click on the installed product in the programs list and select Properties, or launch the product and look in its About/Help section to find the exact version numberAffected if The installed version matches exactly: AVG 7.5.431, Comodo 2.3.6.81, Filseclab 3.0.8686, Antihook 3.0.23, Look N Stop 2.05p2, or Sygate 5.6.2808
-
Verify PEB-based process monitoring is activeExamine the firewall or antihook configuration for process protection rules. In the product settings, look for process control, application control, or program monitoring features that rely on reading PEB fields (ImagePathName, CommandLine, or WindowTitle)Affected if The product has process-based security controls enabled that rely on reading PEB information from running processes
-
Confirm process spoofing is possibleUse a process viewer tool (such as Process Explorer from Sysinternals) to inspect the PEB fields of a test process and verify they can be modified, or check if the firewall allows whitelisting by process name alone without cryptographic verificationAffected if The product identifies trusted processes solely by PEB data (process name, path, or command line) without additional verification like digital signatures or cryptographic hashes
A system is affected if any of the six listed products are installed at the exact vulnerable version and the product's process-based security controls rely on PEB data for identification without additional verification mechanisms.

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 dataImplement more robust process verification methods that do not rely solely on PEB data, such as using cryptographic process signatures, verified digital certificates, or multiple independent verification mechanisms.
