This month's edition of Microsoft's Patch Tuesday features patches for 15 vulnerabilities in Windows, Windows Server, Excel and Word. One of the updates fixes a critical drive-by bug, but the good news is that none of these bugs apply to Windows 7.
The 15 flaws fixed in Tuesday's six security updates were less than half the record 34 Microsoft patched last month in 13 separate bulletins. Of today's 15 bugs, three were tagged "critical" by Microsoft, while the remaining 12 were labeled as "important," the next-lowest rating in the company's four-step severity scoring system.
Experts agreed that users should focus on MS09-065 first and foremost. That update, which was ranked critical, affects all still-supported editions of Windows with the exception of Windows 7 and its server sibling, Windows Server 2008 R2.
