Affected operating systems will include various flavors of Windows XP, Windows Server 2003, Windows Vista, Windows Server 2008, and Windows 7. Various versions of Microsoft XP, Office 2003, Office 2007, and Office 2101. Microsoft Office Sharepoint Server 2007 doesn't escape either.
That's a serious line-up of flaws. However, according to this story from Mathew J. Schwartz, many companies may be planning to skip December and patch next month instead:
Expect enterprises to punt many of these patches until 2011. "The high number of advisories will present a challenge to all Windows system administrators, especially with the holidays shortening the available working hours," said Wolfgang Kandek, CTO of Qualys.
All types of attackers bank of the fact that IT teams are unstaffed and over-partied during the holiday season. In fact, if your organization is being targeted expect an escalation of breach attempts during the holidays. The attackers know you are short staffed. They know your mind is elsewhere. And they know it's human nature to try to put off any absolutely unnecessary work until next year.
Don't be surprised to see a significant amount of exploit software and attacks targeting these vulnerabilities as we head closer to the new year.
So do yourself and your organization a favor: test and deploy these patches before shutting down for the year.
