PHP Resource Management Errors Vulnerability - CVE-2015-8877
The gdImageScaleTwoPass function in gd_interpolation.c in the GD Graphics Library (aka libgd) before 2.2.0 as used in PHP before 5.6.12 uses inconsistent allocate and free approaches which allows remote attackers to cause a denial of service (memory consumption) via a crafted call as demonstrated by a call to the PHP imagescale function.
