Updates for Office 2004, 2008 and 2011 for Mac
Users of Microsoft's Office for Mac should activate the update feature as Microsoft has released updates for Office 2004 for Mac, Office 2008 for Mac and Office 2011 for Mac. All three releases fix a hole in Microsoft Excel which potentially allows remote code execution with the use of specially crafted spreadsheets. Code executed would run with the privileges of the logged-in user. Exploits for the Mac have not been seen to date. The issues have already been fixed in the Windows version of Excel.
The issues also affect Open XML File Format Converter for Mac. The updates range in size from 13 MB for the Office 2004 version to 333 MB for the Office 2008 version. Users can download the updates from the relevant advisory pages or by selecting Help->Check for Updates. According to Microsoft, the Office 2011 update also has improved stability and has other non-security related bug fixes.
