CRITICAL · CVSS 3.1 · EPSS 6.5% (pctl 94)
In your normal cycle
Critical by CVSS (9.8), but no sign of active exploitation.
Description
The exif_process_TIFF_in_JPEG function in ext/exif/exif.c in PHP before 5.5.35, 5.6.x before 5.6.21, and 7.x before 7.0.6 does not validate TIFF start data, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via crafted header data.
