According to security bulletins posted by the software giant, the vulnerabilities involve the Word and Excel components of Office. In both cases, the reported vulnerabilities could have allowed remote code execution if a user opened specially crafted Word or Excel files. The security update fixes 11 vulnerabilities in Word and 13 in Excel, Microsoft says.
Affected Mac products include Office 2004, Office 2008, and Open XML File Format Converter for Mac, which lets users open files created in Office 2008 in earlier versions of the productivity suite.
Office 2008 for Mac 12.2.7 weighs in at 333MB and requires OS X 10.4.9 or later. In addition to the security fixes, the Office 2008 update also promises stability improvements involving Excel crashes at launch and improved reliability for when Entourage connects with a Microsoft Exchange Server.
In addition to the three security updates, Microsoft also released a 64MB update for Microsoft Entourage 2008 for Mac, Web Services Edition. The release notes promise calendaring improvements as well as the ability to synchronise notes, tasks, and categories with Exchange Server. Microsoft says the update also enables logging that can be used for diagnostic purposes.
Later this month, Microsoft will ship a massive overhaul to its collection of productivity applications. Office for Mac Home and Student 2011 will feature new versions of Excel, Word, PowerPoint, and Messenger, while Office for Mac Home and Business will offer those programs plus the new Outlook for Mac 2010.
