Both Storms and Cluley noted the significant outlay Adobe expects users to make to quash the bugs.

Upgrade prices for the three affected applications are $199 each; an upgrade to CS6 Design & Web Premium, the least-expensive edition that includes all three, runs $375. "That's no small bit of change," said Storms.

Adobe today confirmed that the older software would not be patched, and explained why it wouldn't update those editions.

"No dot release was scheduled or released for Adobe Photoshop CS5," said a company spokeswoman. "In looking at all aspects, including the vulnerabilities themselves and the threat landscape, the team did not believe the real-world risk to customers warranted an out-of-band release for the CS5 version to resolve these issues."

That's just tempting fate.
