AhnLab V3 2008.12.4.1 and possibly 2008.9.13.0, when Internet Explorer 6 or 7 is used, allows remote attackers to bypass detection of malware in an HTML document by placing an MZ header (aka "EXE info") at the beginning, and modifying the filename to have (1) no extension, (2) a .txt extension, or (3) a .jpg extension, as demonstrated by a document containing a CVE-2006-5745 exploit.

AhnLab Antivirus 3 Internet Security 2008 Platinum appends data to a filename string at a location indicated by the "Filename length" field in a ZIP header, which allows remote attackers to cause a denial of service (machine crash) and possibly execute arbitrary code via a ZIP file in which this field's value is larger than the actual number of bytes in the filename.
