H Security reports Adobe has issued security updates for Photoshop, Illustrator and Flash Professional, but only for the latest versions. The company urges users to shelve out money for upgrading, or to "follow security best practices and exercise caution when opening files from unknown or untrusted sources".
Adobe logo Users who want to protect their Photoshop, Illustrator or Flash Professional installations against critical security holes must now dig deep into their pockets. It costs £190.80 ($199) to upgrade from a previous version to Photoshop CS6 alone, and this update is recommended by Adobe because it fixes several critical security holes. The other upgrades, for Illustrator and Flash Professional, which close security holes are also exclusively available to paying customers. The only free update Adobe has released on its May patch day is one for Shockwave.
Those who don't want to purchase these commercial upgrades – for example, because they don't need the new Photoshop features – are on their own. Adobe only makes the general recommendation that its customers should "follow security best practices and exercise caution when opening files from unknown or untrusted sources" as the holes do represent substantial threats.
