Bug 'resurrects' deleted image thumbnails in iOS 7 Photos app, dates back to iOS 5

post #1 of 11
Thread Starter 
Despite being discovered in iOS 5 last year, a possible caching bug in Apple's iOS 7 Photos app still allows thumbnails of deleted pictures to be "resurrected" by saving a transparent PNG file to the album.

Thumbs
Example of thumbnail restoration.


The thumbnail restoration issue as applicable to the latest iOS 7.0.4 was spotted by AppleInsider reader Mike, while a quick check confirms that the small previews associated with deleted pictures do indeed reappear when a transparent image is saved to the Camera Roll. Full size pictures are not restored.

One of the first mentions of the Photos app bug appeared in Apple's Support Communities forum in early 2012, with the thread creator stating they were able to "resurrect" photos deleted some months prior by saving an image with a transparent background to their photo album.

A closer inspection of the issue revealed that only image previews, or small thumbnails, were being restored, suggesting the problem was related to an iOS local caching mechanism.

By viewing iOS system files via third-party software, thumbnail files appear in the Photo Data folder even after their associated pictures are deleted. Erasing these files will clear the problem, though the solution is temporary as the system will start saving thumbnails in the same problematic manner once a new photo is taken.

For many, the apparent bug is likely a non-issue, though some users may be concerned about potential security and privacy implications. For example, if a nefarious party were to gain access to an unlocked iOS device, they could potentially restore old deleted thumbnails by saving a transparent PNG file readily available on the Internet.

It is not clear why Apple has left the the possible security hole unpatched, though the company told Mike that iOS engineers would be informed of the issue.

"It's okay honey... You're beautiful... I'll delete the photos right in front of your eyes, promise!"

 

Watch out ladies... :wow:

It restored a recently deleted image (as thumbnail) but it didn't go far into the past for me.

Talk about potentially. Lol

This bug went WAY in to the past for me! And a high-DPI "thumbnail" is about as good as a cell phone photo used to be, once you enlarge it.

Not something that should have been allowed to go on for such a long time. Hopefully easy to fix once Apple decides to actually pay attention to it!

I can just imagine what is going on in the Apple software bug fix dept:

'Oh damn it! When are we gonna get to that bloody thing!'
(iOS7, double devices for each level, new OSX and iOS integration...)

I discovered this bug last year for a different reason... I used iTunes to remove all the photos from my phone and the 'usage' section in the settings said I was still using over 1GB of data for photos. I used iPhone Explorer to take a look at the filesystem and sure enough: There were thumbnail cache files over 1GB in size.

I deleted about 6,000 photos, but I've had an iPhone since day 1 in 2007, so who knows when the bug appeared and how many thumbnails from deleted pictures were in there... I don't really care if you can resurrect old photos on my phone (if you have my phone it's game over anyway), but wasting 1GB of space is not cool.

I discovered this bug when I was in Vegas. The place you *don't* want photos being resurrected from :-)

If someone has physical access to your phone, unlocked, to do anything with this bug you have much much bigger problems

With iExplorer you can get to it even if the phone is locked.
