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 gdImageCreate function in gd.c in the GD Graphics Library (aka libgd) before 2.0.34RC1, as used in PHP before 5.5.37, 5.6.x before 5.6.23, and 7.x before 7.0.8, allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted image dimensions.
