Details

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.
