Doc Text:
A flaw was found in the `golang.org/x/image/webp` library's WebP decoder. A remote attacker could exploit this vulnerability by providing a specially crafted WebP image containing a VP8 chunk with mismatched dimensions. This could cause the decoder to panic, leading to a denial of service (DoS) for applications processing such images.
