CVE-2006-6619
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 · uneditedAVG Anti-Virus plus Firewall 7.5.431 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 confidenceAVG Anti-Virus plus Firewall 7.5.431 relies on the Process Environment Block (PEB) to identify processes for its security controls. Local attackers can spoof the ImagePathName, CommandLine, and WindowTitle fields in the PEB to bypass the anti-virus and firewall protections, allowing malicious processes to operate undetected.

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 from AVG 7.5.431 to a current supported version that does not rely solely on PEB for process identification, or implement additional process verification mechanisms beyond PEB-based detection.
