NVD Description

Note: Versions mentioned in the description apply only to the upstream php7.0 package and not the php7.0 package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

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.
