Today on the Microsoft Security Response Center Blog:
Under the policy, developers will have a maximum of 180 days to submit an updated app for security vulnerabilities that are not under active attack and are rated Critical or Important according to the Microsoft Security Response Center rating system. The updated app must be submitted to the store within 180 days of the first report that reproduces the issue. Microsoft reserves the right to take swift action in all cases, which may include immediate removal of the app from the store, and will exercise its discretion on a case-by-case basis.
But the best part:
If you have discovered a vulnerability in a store application and have unsuccessfully attempted to work with the developer to address it, you can request assistance by contacting secure@microsoft.com.
Clear, concise, and puts users first. My understanding is that Apple is also pretty tight on suspending vulnerable apps, but they don’t have it formalized into visible policy, with a single contact point. If anyone knows Google’s policy (formal or otherwise), please drop it in the comments, but that is clearly a different ecosystem.
