Microsoft Patch Release Causes Disruption

Lumension Security : 10 February, 2011  (Technical Article)
A total of twelve bulletins with three critical amongst them causes significant disruption to IT users
Paul Henry, security and forensic analyst at Lumension comments on Patch Tuesday:



“This is a very disruptive Patch Tuesday with several updates impacting nearly the full operating system product line from Microsoft and requiring a reboot. While a pair of Zero Day security issues have now been patched, we still have not received a patch for the MHTML issue that impacts all versions of Internet Explorer, meaning we can look forward to an equally disruptive Patch Tuesday in March.



“We finally got our patch for Internet Explorer in the midst of Microsoft’s 12 bulletins; three of which were critical and nine important. 900 million people are now sharing the love for Microsoft after last month, when we waited for the IE patch that never came. This month, we get to celebrate the national day of love by simultaneously rebooting our PCs.



“The IE patch is making a lot of noise, addressing the current IE CSS recursive style sheet import issue. History is repeating itself with this massive reboot and as we know from experience, reboots of this magnitude have been known to upset services and applications, so it’s possible we will see similar problems to  what we encountered in 2007 when a large Microsoft Patch that required a reboot crippled applications, Skype in particular.



“Also addressed today were the Windows graphics rendering issue, the DIB thumbnail bug and updates from Adobe and Mozilla.  Adobe will be releasing updates for several Adobe Reader versions for both Windows and Macintosh, and Mozilla will be releasing two Firefox version updates that will address security issues on February 14, 2011. Although Microsoft appears to be doing a bit of spring cleaning this Patch Tuesday, along with a lot of ‘run of the mill’ stuff, it cannot be emphasized enough that this will create the need for a massive simultaneous reboot and historically, we’ve seen services greatly impacted when such a huge number of machines require reboots.”
