The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition in exif_process_SOFn within the PHP EXIF component. A remote attacker can create a specially crafted image file, pass it to the affected application, trigger out-of-bounds read error and read contents of memory on the system.
