Description

A remote overflow exists in GD Graphics Library. GD Graphics Library fails to check for an integer overflow when allocating memory for PNG image files in the gd_png.c gdImageCreateFromPngCtx() function. Using a specially crafted PNG image file, an attacker can cause a heap overflow and as a result remotely execute arbitrary code, leading to a loss of integrity.
