Mandriva Linux Security Advisory 2013-087 - Mozilla community member Tobias Schula reported that if gfx.color_management.enablev4 preference is enabled manually in about:config, some grayscale PNG images will be rendered incorrectly and cause memory corruption during PNG decoding when certain color profiles are in use. A crafted PNG image could use this flaw to leak data through rendered images drawing from random memory. By default, this preference is not enabled. Various other issues were also addressed.
