CVE-2005-3372 · MEDIUM Severity

AV:N/AC:H/AU:N/C:P/I:P/A:P

Multiple interpretation error in eTrust CA 7.0.1.4 with the 11.9.1 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."
