iMessage - Decoding NSSharedKeyDictionary can read ObjC Object at Attacker Controlled Address

During processing of incoming iMessages, attacker controlled data is deserialized using the NSUnarchiver API. One of the classes that is allowed to be decoded from the incoming data is NSDictionary. However, due to the logic of NSUnarchiver, all subclasses of NSDictionary that also implement secu...

Via NSUnarchiver we can read NSBuiltinCharacterSet with a controlled serialized state. It reads a controlled int using decodeValueOfObjCType:"i" then either passes it to CFCharacterSetGetPredefined or uses it directly to manipulate NSBuiltinSetTable. Neither path has any bounds checking and the...
