Summary
libheif vulnerabilities
Details

Xianrui Dong discovered that libheif had an out-of-bounds read in its HEIF sequence track parser. An attacker could possibly use this issue to cause a denial of service or obtain sensitive information. This issue only affected Ubuntu 26.04 LTS. (CVE-2026-47254)

Junyi Liu discovered that libheif had a null pointer dereference in its image tiling interface. An attacker could possibly use this issue to cause a denial of service. (CVE-2026-47709)

Calvin Young and Enoch Chow discovered that libheif had an integer overflow in its inline mask size calculation. An attacker could possibly use this issue to cause a denial of service or obtain sensitive information. (CVE-2026-47714)

Ariel Koren discovered that libheif had an integer underflow in its grid image tile coordinate transform. An attacker could possibly use this issue to cause a denial of service or obtain sensitive information. (CVE-2026-48029)

It was discovered that libheif had a missing bound check in its HEIF sequence parser, allowing unbounded heap allocation. An attacker could possibly use this issue to cause a denial of service. (CVE-2026-50142)
