PHP Out-of-bounds Write Vulnerability - CVE-2016-7126

Critical
Reference: CVE-2016-7126
NVD Link: https://nvd.nist.gov/vuln/detail/CVE-2016-7126
Title: PHP Out-of-bounds Write Vulnerability
Overview:

The imagetruecolortopalette function in ext/gd/gd.c in PHP before 5.6.25 and 7.x before 7.0.10 does not properly validate the number of colors which allows remote attackers to cause a denial of service (select_colors allocation error and out-of-bounds write) or possibly have unspecified other impact via a large value in the third argument.
