Microsoft has started the year with a truly unusual Patch Tuesday. There are nine updates for January, with six rated as critical and the remaining three rated as important (the reverse of the usual distribution in terms of severity). January has a couple of additional surprises. First, it looks like MS16-009 did not make this Patch Tuesday release at all and may only surface later this month. Secondly, we see what has been rated as an important update with MS16-008 may contain the most severe vulnerability and the most risky patch contents.
Thanks to Shavlik this month for their very helpful summary infographic detailing this January Patch Tuesday.
