Description Andrej Nemec 2016-05-23 15:34:20 UTC
A vulnerability was found in the GD Graphics Library before 2.2.0, as used in PHP before 5.6.12. The gdImageScaleTwoPass function in gd_interpolation.c 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.
