Описание
The exif_convert_any_to_int function in ext/exif/exif.c in PHP before 5.6.30, 7.0.x before 7.0.15, and 7.1.x before 7.1.1 allows remote attackers to cause a denial of service (application crash) via crafted EXIF data that triggers an attempt to divide the minimum representable negative integer by -1.
It was found that the exif_convert_any_to_int() function in PHP was vulnerable to floating point exceptions when parsing tags in image files. A remote attacker with the ability to upload a malicious image could crash PHP, causing a Denial of Service.
