Huh? I could've sworn the TIFF bug was during the iPhoneOS 1.x days. I recall jailbreakme's exploit using corrupted fonts in a PDF, not TIFF images. A quick Google search led me to this https://appleinsider.com/articles/10/08/03/browser_based_ios_jailbreak_utilizes_scary_pdf_security_hole https://appleinsider.com/articles/10/08/03/browser_based_ios...
- dunham 3y agoYeah, the tiff bug was one of the the first few iOS jailbreaks. The wiki says 1.0-1.1.1: https://www.theiphonewiki.com/wiki/LibTiff_Exploit https://www.theiphonewiki.com/wiki/LibTiff_Exploit I wrote a patch to fix it that one of the jailbreaks used. I wasn't in the scene, but wanted to protect my ipod touch. So I figured out a patch and gave it to somebody named "pumpkin" on IRC. It's been a long time, but I remember it was fun to learn ARM assembly and figure out how to rewrite the code to get enough space to insert a test and return.
- hot_gril 3y agoYou're right, iOS 4 jailbreakme was PDF. But jailbreakme also existed for 1.x, using TIFF. https://en.wikipedia.org/wiki/JailbreakMe https://en.wikipedia.org/wiki/JailbreakMe
