With this December Patch Tuesday, we see a smaller number of patches than expected, with three updates rated as critical and four patches that Microsoft has rated as important. This month, we also see the much delayed Microsoft Exchange update (MS14-075) released as part of the December cycle. Historically speaking, this month is a light release as in the past we have seen up to 14 patches released by Microsoft for December (see Patch Tuesday December 2010). In addition to the December releases, Microsoft has also updated two patches from the November cohort. MS14-65 was updated to address a memory corruption vulnerability in Internet Explorer that could have led to a denial of service scenario. MS14-066 was also updated to resolve a problem with the patch that affected Windows Vista and Server 2003 users. In addition to these Microsoft patches, there is a critical update from Adobe for Flash Player that is probably the most important update to deploy this month.
