CVE-2016-7126

CRITICAL

PHP < 5.6.25 and 7.x < 7.0.10 - Out-of-bounds Write via imagetruecolortopalette

Title source: llm
STIX 2.1

Description

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.
