How to fix?

Upgrade Debian:9 libgd2 to version 2.2.3-87-gd0fec80-1 or higher.

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.

Integer overflow in the gdImageWebpCtx function in gd_webp.c in the GD Graphics Library (aka libgd) through 2.2.3, as used in PHP through 7.0.11, allows remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via crafted imagewebp and imagedestroy calls.
