CVE-2005-3378 is a vulnerability of currently unknown severity. Multiple interpretation error in Norman 5.81 with the 5.83.02 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.". EPSS estimates a 2.35% chance of exploitation in the next 30 days.
