CVE-2014-3670

The exif_ifd_make_value function in exif.c in the EXIF extension in PHP
before 5.4.34, 5.5.x before 5.5.18, and 5.6.x before 5.6.2 operates on
floating-point arrays incorrectly, which allows remote attackers to cause a
denial of service (heap memory corruption and application crash) or
possibly execute arbitrary code via a crafted JPEG image with TIFF
thumbnail data that is improperly handled by the exif_thumbnail function.
