+This patch is adapted from commit a11f47475e6443b7f32d21f2271f28f417e2ac04 and

+Subject: [PATCH] Fix #420: Potential infinite loop in gdImageCreateFromGifCtx
+
+Due to a signedness confusion in `GetCode_` a corrupt GIF file can
+trigger an infinite loop. Furthermore we make sure that a GIF without
+any palette entries is treated as invalid *after* open palette entries
+have been removed.
+
+CVE-2018-5711
+
+See also https://bugs.php.net/bug.php?id=75571.
