CVE-2005-3370 (CCN-24579)

Assigned:2005-10-25
Published:2005-10-25
Updated:2016-10-18
Summary:Multiple interpretation error in ArcaVir 2005 package 2005-06-21 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."
