+Subject: [PATCH 2/8] Fix image handling integer overflows
+
+Image loading memory allocation is based on the image width and height:
+ malloc(heigth * width * 3).  Providing an image with large height and
+width values can cause the result of this calculation to exceed the
+maximum value of an unsigned int and thus causes an integer overflow.
+The result: too little memory is allocated and an heap overflow occurs.
+
+This patch was based by Niels Heinen <niels@freebsd.org>
+Thanks!
