6 Security Bulletins were released – 3 Critical, 3 Important, and 0 Moderate
This Month In Brief
We have not uncovered any widespread problems with any of these patches and are releasing all of them.
MS15-106, MS15-108 and MS15-109 are rated Critical. After your next patch cycle completes you should follow up and make sure this is installed.
No out-of-band security updates were released during the last month.
Notable news: The month’s releases breaks the record for the most bulletins released by Microsoft in a single year – and it’s only October. We’re up to 111 and the previous record was 106 in 2013. This doesn’t necessarily mean Microsoft products are less secure these days but it does seem to reflect an increased commitment to address vulnerabilities. Which is a good thing.
