NVD Description

Note: Versions mentioned in the description apply only to the upstream gd package and not the gd package as distributed by Alpine. See How to fix? for Alpine:3.12 relevant fixed versions and status.

gdImageColorMatch in gd_color_match.c in the GD Graphics Library (aka LibGD) 2.2.5, as used in the imagecolormatch function in PHP before 5.6.40, 7.x before 7.1.26, 7.2.x before 7.2.14, and 7.3.x before 7.3.1, has a heap-based buffer overflow. This can be exploited by an attacker who is able to trigger imagecolormatch calls with crafted image data.
