-Subject: [PATCH] gif: Fix LZW decoder accepting invalid LZW code.
-
-The code value after a reset wasn't being validated, which means we would
-accept invalid codes. This could cause an infinite loop in the decoder.

-Fixes CVE-2020-29385

-Fixes https://gitlab.gnome.org/GNOME/gdk-pixbuf/-/issues/164
