CVE-2016-7127

Name of the Vulnerable Software and Affected Versions PHP versions prior to 5.6.25 PHP versions 7.x prior to 7.0.10

Description The issue is related to the imagegammacorrect function in the ext/gd/gd.c file, which does not properly validate gamma values. This allows remote attackers to cause a denial of service (out-of-bounds write) or possibly have other unspecified impacts by providing different signs for the second and third arguments. The vulnerability is associated with an out-of-bounds write in memory.

Recommendations For PHP versions prior to 5.6.25, update to version 5.6.25 or later. For PHP versions 7.x prior to 7.0.10, update to version 7.0.10 or later.
