Description

There exists interger overflows in libvpx in versions prior to 1.14.1. Calling vpx_img_alloc() with a large value of the d_w, d_h, or align parameter may result in integer overflows in the calculations of buffer sizes and offsets and some fields of the returned vpx_image_t struct may be invalid. Calling vpx_img_wrap() with a large value of the d_w, d_h, or stride_align parameter may result in integer overflows in the calculations of buffer sizes and offsets and some fields of the returned vpx_image_t struct may be invalid. We recommend upgrading to version 1.14.1 or beyond

• CWE-190Integer Overflow or WraparoundThe product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
