Last modified Jun 17, 2026

CVE-2016-7127 is a vulnerability of currently unknown severity. The imagegammacorrect function in ext/gd/gd.c in PHP before 5.6.25 and 7.x before 7.0.10 does not properly validate gamma values, which allows remote attackers to cause a denial of service (out-of-bounds write) or possibly have unspecified other impact by providing different signs for the second and third arguments.. EPSS estimates a 6.84% chance of exploitation in the next 30 days.
