CVE-2005-3382
Sophos Anti-Virus 3.91 with Engine 2.28.4 - Virus Scanning Bypass via MZ Magic Byte Sequence
Title source: llmDescription
Multiple interpretation error in Sophos 3.91 with the 2.28.4 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."
