Microsoft Security Update: November Patch Tuesday

Apologies for this late update to our core Patch Tuesday update. Here is a summary of the update ....

The November Patch Tuesday update from Microsoft follows the largest patch and security update in Microsoft’s history. This month there are six updates to Office, Active Directory and Microsoft’s Office application suite.

These six updates have a low impact, bar one patch to Excel which may cause compatibility issues for some applications. The main cause for concern here is that Excel is a primary if not essential element to many environments. For example most banking, trading floor and insurance platforms. Therefore any change must be tested rigorously.

Whilst there are few applications in our sample that are affected, the ChangeBASE AOK team recommends that the Excel update (MS09-067) requires particular attention in any environments where there is a significant dependency on this,

We have included a brief snap-shot of some of the results from our AOK Software that demonstrates some of the potential impacts on Microsoft Office deployments with the following picture.

Testing Summary
MS09-063 : : Marginal impact and negligible testing profile
MS09-064 : : Marginal impact and negligible testing profile
MS09-065 : : Marginal impact and negligible testing profile
MS09-066 : : Marginal impact and negligible testing profile
MS09-067 : : Moderate impact and negligible testing profile
MS09-068 : : Marginal impact and negligible testing profile
