We have not uncovered any widespread problems with any of these patches and are releasing all of them.
MS12-043, MS12-044 and MS12-045 are all rated “Critical”.
MS12-043 (XML core services bug) is the most important patch this month. It is both publicly disclosed and being exploited. Make sure this one gets installed.
Microsoft’s risk assessment warns that MS12-044 and MS12-045 are “Likely to see reliable exploits developed within next 30 days” However MS12-044 only affects IE 9.
No out-of-band updates were released during the last month.
Side Note: All 3 critical patches “could allow remote code execution if a user views a specially crafted webpage” Here is a Microsoft link to “Six tips to help you stay safer online” It’s pretty generic advice we all know but it might be worth sending out to your clients (or using as an outline for something you write) as a reminder that the internet is a dangerous place. You can remind them you already take care of the first tip “Keep all software (including your web browser) current”.
