A vulnerability in the HEIF and AVIF libheif file format decoder is related to the data parsing code
of strided images in the emscripten wrapper for libheif. Exploitation of the vulnerability could allow
an attacker acting remotely to use a specially crafted image file to cause a
buffer overflow in linear memory during a memcpy call.
