Fewer Patches Means More Testing For Microsoft
Patch Tuesday release load gets cut in half, but not because the problems went away.
The company just has a lot more quality assurance work to do.
Microsoft originally planned to release eight security bulletins covering Windows, Office and Visual Studio. However, the company cut that back to four bulletins, removing one related to Office and three related to Visual Studio.
In a roundabout way, a Microsoft (Quote) spokesperson said the company was still testing the fixes, noting that many factors impact the period between the discovery of a vulnerability and the release of a security update.
"Once the update is built, it must be tested with the different operating systems and applications it affects, then localized for many markets and languages across the globe. In some instances, multiple vendors are affected by the same or similar issue, which requires a coordinated release."
In other words, they're still testing the patches.
The fixes that were released cover vulnerabilities in Excel and Outlook as well as yet another Vector Markup Language (VML) problem. Problems have been found in VML before and fixed, but this is a new one.
In addition to the fixes, the Malicious Software Removal Tool has been update to add a new Trojan, Win32/Haxdoor. As is tradition, Microsoft will hold a webcast on Wednesday at 11 a.m. PST to discuss the fixes.
Amol Sarwate, manager of vulnerability research at security firm Qualys, thinks Microsoft was right to hold off on issuing patches that weren't ready, even if that means there are still three Microsoft Word vulnerabilities left to be fixed.
"I think they realized they could not QA and make sure all these patches were ready to go today. So it's a good thing we won't have to re-patch systems for flawed patches," he told internetnews.com.
