CVE-2005-3371: Multiple interpretation error in AVG 7 7.0.323 allows remote attackers to bypass virus scanning via a file...

Multiple interpretation error in AVG 7 7.0.323 allows remote attackers to bypass virus scanning via a file such as BAT, HTML, and EML with an "MZ" magic byte sequence which is normally associated with EXE, which causes the file to be treated as a safe type that could still be executed as a dangerous file type by applications on the end system, as demonstrated by a "triple headed" program that contains EXE, EML, and HTML content, aka the "magic byte bug."

Security readout for executives and security teams

This CVE describes an old AVG 7 scanning weakness where crafted files could be misclassified as safe because they started with bytes usually associated with Windows executables. The business risk is malware or unsafe content slipping past legacy antivirus inspection, especially in email or web-download workflows that still rely on AVG 7-era detection. Exposure is likely limited to environments still running AVG 7 7.0.323 or legacy scanning stacks derived from that behavior. Modern, vendor-supported antivirus deployments are not confirmed affected by the provided sources. Treat this as a legacy exposure issue. It is not a current KEV-backed emergency from the provided evidence, but any remaining AVG 7 dependency should be removed because antivirus bypasses undermine malware controls. Mitigation focus: Check AVG or successor vendor guidance for historical fixes and support status.; Retire or replace any AVG 7 7.0.323 deployments.; Use supported antivirus engines with current content and parser updates..
