Both Apple and Microsoft have released urgent and critical patches for Power Point. Apple has updated OS X 10.5 to 10.5.7, and Microsoft has released its update (MS09-017) nearly concurrently, which address numerous significant security risks. This massive Security update for Apple (442MB in total or 729MB for the combo update) also addresses some stability and capability enhancements for Safari. For Microsoft, the security update covers every single version of Power Point: PowerPoint 2000, 2002 (XP), and 2003 are the versions affected by most of the vulnerabilities, which could lead to remote code execution.
