CVE-2016-7127

原文の説明

The imagegammacorrect function in ext/gd/gd.c in PHP before 5.6.25 and 7.x before 7.0.10 does not properly validate gamma values, which allows remote attackers to cause a denial of service (out-of-bounds write) or possibly have unspecified other impact by providing different signs for the second and third arguments.

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
