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.

The GD Graphics Library (aka LibGD) 2.2.5 has a double free in the gdImage*Ptr() functions in gd_gif_out.c, gd_jpeg.c, and gd_wbmp.c. NOTE: PHP is unaffected.
