Multiple interpretation error in (1) McAfee Internet Security Suite 7.1.5 version 9.1.08 with the 4.4.00 engine and (2) McAfee Corporate 8.0.0 patch 10 with the 4400 engine 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 antivirus scanning bypass in specific McAfee consumer and corporate products. Certain mixed-format files could be classified as safe by the scanner while still being handled as risky content by endpoint applications. The main business risk is misplaced confidence in legacy antivirus controls. Exposure is most likely limited to organizations still running the named 2005-era McAfee products or engines, or relying on archived systems using those scanners for mail, web, or file inspection. The source bundle does not identify modern affected versions. Treat this as a legacy-control risk, not an urgent modern exploit based on the provided evidence. Prioritize confirmation if old McAfee scanners remain in production, regulated archive workflows, or email/file gateways. Mitigation focus: Inventory for the named McAfee versions and engines.; Check McAfee or successor vendor guidance for fixes or migration advice.; Replace unsupported antivirus engines with supported endpoint and gateway controls..
