CVE-2012-1434: The Microsoft EXE file parser in AhnLab V3 Internet Security 2011.01.18.00, Emsisoft Anti-Malware 5.1.0.1,...

Security readout for executives and security teams

This CVE describes a way for specially formed Windows EXE files to slip past malware scanning in several older antivirus products. The issue is not remote code execution in the antivirus itself; the business risk is missed detection, leaving other controls to catch malicious files. Exposure is most plausible where the listed legacy antivirus versions still inspect inbound EXE files, email attachments, web downloads, file shares, or malware repositories. The source bundle does not identify broader product families, current versions, or CPEs. Moderate priority for legacy environments, unknown priority otherwise. This is old and not KEV-listed, but detection bypass can undermine malware defenses if affected scanners remain in production. Mitigation focus: Inventory use of the named antivirus products and exact versions.; Check each vendor’s historical advisory or support guidance for fixes.; Replace unsupported 2011-era engines with maintained security tooling..
