It hasn’t been the first time, that Microsoft revealed some criteria used to develop security updates.

Patch development guidelines (June 2018)

In a paper Microsoft Security Servicing Commitments (PDF document) that was still in draft stage, Microsoft revealed in June 2018 its decision chain for the development of security updates.

  • Does the vulnerability violate a security limit or feature that Microsoft is committed to defending against attacks?
  • Is the severity of the vulnerability so severe that it must be addressed immediately by releasing a security update?

If both questions are answered in the affirmative, Microsoft will start developing a security update and roll it out to the next patchday (Tuesday 2 of the month).

There Microsoft outlines the criteria according to which security measures are taken as soon as a vulnerability is discovered. 

In a second PDF document Microsoft describes how they assigns severity to bug reports. The document reveals which bugs are classified as critical (e.g., a vulnerability allows unauthorized access to the file system), which are important, which bugs are ranked middle, and which are rated low risk. A denial of service error that only causes an application to restart is always considered low-risk. (via)
