Description

The GIF decoding function gdImageCreateFromGifCtx in gd_gif_in.c in the GD Graphics Library (aka libgd), as used in PHP before 5.6.31 and 7.x before 7.1.7, does not zero colorMap arrays before use. A specially crafted GIF image could use the uninitialized tables to read ~700 bytes from the top of the stack, potentially disclosing sensitive information. A data leak was found in gdImageCreateFromGifCtx() in GD Graphics Library used in PHP before 5.6.31 and 7.1.7. An attacker could craft a malicious GIF image and read up to 762 bytes from stack.
