Microsoft Excel Viewer (aka Xlview.exe) and Excel in Microsoft Office 2007 (aka Office 12) allow remote attackers to cause a denial of service (read access violation and application crash) via a crafted spreadsheet file, as demonstrated by a .xls file with battery voltage data.

Microsoft Office Excel 2007 Gold and SP1 does not properly delete the PWD (password) string from connections.xml when a .xlsx file is configured not to save the remote data session password, which allows local users to obtain sensitive information and obtain access to a remote data source, aka the "Excel Credential Caching Vulnerability."

A "memory calculation error" in Microsoft Office PowerPoint 2000 SP3, 2002 SP3, 2003 SP2, and 2007 through SP1; Office Compatibility Pack for Word, Excel, and PowerPoint 2007 through SP1; and Office 2004 for Mac allows remote attackers to execute arbitrary code via a PowerPoint file with crafted list values that trigger memory corruption, aka "Parsing Overflow Vulnerability."
