There is a vulnerability in the strided image data parsing code in the emscripten wrapper for libheif. An attacker could exploit this through a crafted image file to cause a buffer overflow in linear memory during a memcpy call.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

    It was discovered that there were two issues in libheif, a decoder     and encoder for the HEIF and AVIF image formats that could have been     exploited by specially-crafted image files.

    For Debian 11 bullseye, these problems have been fixed in version     1.11.0-1+deb11u2.

    We recommend that you upgrade your libheif packages.
