Attack Code Found For Recent Windows Bug
CWmike writes "Just a day after downplaying the vulnerability that caused it to issue an out-of-cycle patch last week, Microsoft warned customers late yesterday that exploit code had gone public and was being used in additional attacks. 'We've identified the public availability of exploit code that now shows code execution for the vulnerability addressed by MS08-067,' said Mike Reavey, operations manager of Microsoft's Security Response Center, in a post to the MSRC blog. 'This exploit code has been shown to result in remote code execution on Windows Server 2003, Windows XP, and Windows 2000.'"
If you were MS, and wanted to brag about 5 Nines uptime, wouldn't you design the patch so you didn't have to reboot production servers once a month?
5 nines is ~5.3 minutes downtime per year
You don't acheive that with a single Linux box either, unless you simply aren't keeping it up to date, even if you manage to avoid 'rebooting it' you are still going to have serious trouble reliably preventing 'unavailability of services' from reaching 5.3 minutes over a year.
It takes either a mainframe or a cluster to reach 5 9's with any reliability. Windows doesn't run on a mainframe, and if you have cluster, a few scheduled reboots now and then don't result in any downtime, since you don't have to bring the entire cluster down.
So your argument really doesn't apply.
