"exif_process_IFD_in_MAKERNOTE in ext/exif/exif.c in PHP 7.2.x before

file.(CVE-2018-14851)

exif_read_from_impl in ext/exif/exif.c in PHP 7.2.x through 7.2.7
allows attackers to trigger a use-after-free (in exif_read_from_file)

vulnerable code is reachable through the PHP exif_read_data
function.(CVE-2018-12882)

An issue was discovered in PHP 7.2.x before 7.2.8. An Integer Overflow
leads to a heap-based buffer over-read in exif_thumbnail_extract of
