CVE-2007-0028

Microsoft Excel 2000, 2002, 2003, Viewer 2003, Office 2004 for Mac, and Office v.X for Mac does not properly handle cert

Microsoft Excel 2000, 2002, 2003, Viewer 2003, Office 2004 for Mac, and Office v.X for Mac does not properly handle certain opcodes, which allows user-assisted remote attackers to execute arbitrary code via a crafted XLS file, which results in an "Improper Memory Access Vulnerability." NOTE: an early disclosure of this issue used CVE-2006-3432, but only CVE-2007-0028 should be used.
