Following in Microsoft's footsteps with its monthly 'Patch Tuesday' approach to system security, Adobe said it will stick to a quarterly release schedule for security updates of its own.

"Based on feedback from our customers, who have processes and resources geared toward Microsoft’s “Patch Tuesday” security updates, we will make Adobe’s quarterly patches available on the same days. (Although our 3/10/09 and 5/12/09 security patches landed on Patch Tuesday, the timing was coincidental. In both cases, we shipped the patches as soon as we finished testing them.)," Brad Arkin, Adobe director of product security and privacy, wrote in a blog post.

In March, Adobe released a patch that fixed a critical vulnerability in Adobe Reader 9 and Acrobat 9 that would have allowed an attacker to gain complete control of victim's PC. According to Arkin, this security hole led to the company's decision to implement scheduled security updates.
