Microsoft has re-released the critical MS07-036 bulletin to add protection for Mac OS X users.
When the bulletin was originally released in this month's Patch Tuesday batch, there was no mention of Mac users being at risk but the bulletin was reissued late Thursday night with a note that all three vulnerabilities affect the Microsoft Office 2004 for Mac software.
The Office 2004 for Mac portion of the bulletin is rated "important" across the board for all three flaws. A successful attack could lead to remote code execution on the affected system.
The reissued bulletin also includes updated File Manifest information for Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint 2007.
