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 · unedited
AVG 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 confidence

AVG 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.

MitigationUpgrade 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.
