Affected: struktur libheif

In Libheif 1.17.6, insufficient checks in ImageOverlay::parse() decoding a heif file containing an overlay image with forged offsets can lead to an out-of-bounds read and write.

Affected: Ubuntu:24.04:LTS: libheif

Gerrard Tai discovered that libheif did not properly validate certain images, leading to out-of-bounds read and write vulnerability. If a user or automated system were tricked into opening a specially crafted file, an attacker could possibly use this issue to cause a denial of service or to obtain sensitive information.
