Adobe to fix Flash Player on Patch Tuesdays

Adobe has changed its schedule for releasing Flash Player security updates to coincide with Microsoft's Patch Tuesday schedule.

"Microsoft and Adobe are now officially married," joked Andrew Storms, director of security operations at nCircle Security, a software vendor, in an email. "They started dating when they decided to share the MAPP program," and once Microsoft agreed to embed Flash into Internet Explorer 10, it was "inevitable" that Adobe would begin following Microsoft's patch schedule, he said.

Under MAPP, or the Microsoft Active Protections Program, Microsoft provides select security vendors with prepatch information to give them time to craft detection signatures for new exploits or malware.

In July 2010, Adobe began using MAPP to deliver vulnerability information about its own products to security firms. Microsoft issues its security updates on the second Tuesday of each month. Until now, Adobe has released Flash bug fixes at irregular intervals.

The lack of synchronization became an issue after Microsoft announced it would bake Flash Player into IE10 for Windows 8 and its tablet spin-off, Windows RT. Problems surfaced in September when Microsoft said it would not patch IE10 for at least six weeks, even though Adobe had issued updates the previous month that addressed at least one vulnerability that hackers were already exploiting.

Microsoft later recanted and issued an update to IE10. It then issued another in October, on the same day Adobe shipped its Flash fixes. Some criticized Microsoft for breaking its schedule and confusing customers.

Now, however, some security professionals are praising Adobe's change. "Concentrating updates on a single day is a benefit for any organization," said Wolfgang Kandek, CTO of security vendor Qualys, in an email. "[The new schedule] should streamline rollouts and get Flash updates [installed] more widely."
