Maliciously coded GIF files could cause Photoshop to crash, so the team has posted an update. If you open GIFs in Photoshop, please download the update for Mac, Win64, and/or Win32. They recommend making certain that you’re running the most recent version of Photoshop. To check/update, choose Help->Updates inside Photoshop CS5 and apply all of the updates listed under Adobe Photoshop CS5.
Are earlier versions of CS vulnerable? Thank you.
[As far as I know it’s CS5-specific. –J.]
This update isn’t appearing in the auto-updater.
[Sorry, I should have been clearer in my wording: the update is only on Adobe.com. The text about the updater pertains only to the PS updates that one should run beforehand. –J.]
