CVE-2016-7126

原文の説明

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.

影響を受けるソフトウェア

• PHP = 7.0.2= 7.0.3≤ 5.6.24= 7.0.5= 7.0.9= 7.0.7 完全一致
