There exists interger overflows in libvpx in versions prior to 1.14.1. Calling vpximgalloc() with a large value of the dw, dh, or align parameter may result in integer overflows in the calculations of buffer sizes and offsets and some fields of the returned vpximaget struct may be invalid. Calling vpximgwrap() with a large value of the dw, dh, or stridealign parameter may result in integer overflows in the calculations of buffer sizes and offsets and some fields of the returned vpximage_t struct may be invalid. We recommend upgrading to version 1.14.1 or beyond
