NVD Description

Note: Versions mentioned in the description apply only to the upstream libgd2 package and not the libgd2 package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

gd_gif_in.c in the GD Graphics Library (aka libgd), as used in PHP before 5.6.33, 7.0.x before 7.0.27, 7.1.x before 7.1.13, and 7.2.x before 7.2.1, has an integer signedness error that leads to an infinite loop via a crafted GIF file, as demonstrated by a call to the imagecreatefromgif or imagecreatefromstring PHP function. This is related to GetCode_ and gdImageCreateFromGifCtx.
