P: Photoshop 23.0 - cannot open TIF files, generated in other programs

Starting from version 22.5.2 Photoshop stopped opening some tif files. The issue is related to a previously discovered vulnerability, the escalation of which, under certain conditions, may lead to arbitrary code execution - Adobe Security Bulletin.

 

Important: The problem is not with Photoshop, but with third-party software developers who do not keep track of current TIF specifications

 

A temporary solution to the problem is to convert files in third-party editors that completely update the structure of TIF files (for example, xnView, ImageMagik, etc.); such files can also be converted using the Camera Raw plug-in (via Bridge).

We all hope that Adobe can solve this problem and find a way to bring third-party files to modern standard. But I recommend that you independently contact the developers of programs whose files Photoshop cannot open. Notify them of the problem, recommend to contact @J453 using this community. Jeffrey can provide technical information to developers to solve this problem.

There are no problems (or solved):

    Thanks for the update. Will there also be a 23.0.3 build with this TIF change?

    It seems to have fixed our problems with images created from Imagemagick and Apple Preview 🙂

        Hi Jeff, what about tiled TIFFs? It seems that the new Photoshop rejects our tiled tiffs for the very same reason: because of the missing RowsPerStrip (278) entry? To my understanding it is not intended to write tiled tiffs with the RowsPerStrip (278) entry. What can we do about that?

          @Stellar_gift16B8 Feel free to post or DM me a link to a Tiled TIFF from your workflow so I can have engineering regress any changes with it.

            @J453 Please do. Tiled Tiff files seem to be the cause of the error with all the existing files I have produced from Ultramap. Outputting files as scanline/interleaved, versus tiled/interleaved, resolves the file opening error. I have set all of my outputs as tiled, until now, since my orthophoto software requires tiled tifs and converts them before they can be imported.

              We are looking at one more flavor of TIFF (tiled) to allow/support.

                @Barry Rudick If you're running 23.0.1 or later, Photoshop will reject TIFFs that lacked an attribute which could pose a security risk.

                Responding to Jeff's post:

                 

                That seems like the likely plan to follow.

                 

                It is interesting that opening and closing takes care of the problem. But I assume that PS would see an "infected" TIFF and not allow it's use?

                 

                Should all incoming TIFF files (we are a fine art printng company) be suspect? Is there a sniffer program to check?

                 

                Thanks for the info.

                  To be clear, this is a security issue, not a "restrictive TIFF specification." TIFF is actually very open and has lot of flexibility but applications which don't follow a standard are always at the risk of being hijacked by exploits, and those are hard to fix after the fact.

                  Since TIFF is open, I would expect that image processing developers and image libraries will all incorporate some kind of fix in the future, but you may just be out of luck with an older and unsupported app. This is one valid argument put forth by those in the Free Software movement.

                  Now that the exploit is public, don't be surprised to see files floating around which could be a security risk.
