Adobe's recent release of patches for Photoshop, Illustrator, Flash Professional, and Shockwave have all been marked critical by the company, but users will be required to pay out of their own pocket for almost all of them.
All of the related vulnerabilities, found in each of Adobe's four software suites, have the potential to allow a remote user to execute arbitrary code and take complete control of the user's computer. While the patch for Shockwave is free, no such patch is available for CS5.5, or earlier versions of Photoshop, Illustrator, and Flash Professional. Instead, users concerned about the vulnerabilities in these products will be required to purchase upgrades of each product.
According to Adobe's site, it will cost at least $199 U.S. to upgrade to Photoshop CS6, $249 to upgrade to Illustrator CS6, and $99 to upgrade to Flash Professional CS6.
