ExifInterface: Prevent infinite loop A corrupted image file may create two problems. 1. A corrupted IFD pointer may point to an IFD that has already been read, thus creating an infinite loop and a stack overflow. 2. A corrupted IFD offset value may have a negative value, thus prompting a random reading of the file and creating an infinite loop. This CL addresses these issues.
