Webmproject: Security Vulnerabilities
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

There exists a use after free/double free in libwebp. An attacker can use the ApplyFiltersAndEncode() function and loop through to free best.bw and assign best = trial pointer. The second loop will then return 0 because of an Out of memory error in VP8 encoder, the pointer is still assigned to trial and the AddressSanitizer will attempt a double free.
