{"id":"USN-8526-1","summary":"libheif vulnerabilities","details":"Xianrui Dong discovered that libheif had an out-of-bounds read in its\nHEIF sequence track parser. An attacker could possibly use this issue\nto cause a denial of service or obtain sensitive information. This issue\nonly affected Ubuntu 26.04 LTS. (CVE-2026-47254)\n\nJunyi Liu discovered that libheif had a null pointer dereference in its\nimage tiling interface. An attacker could possibly use this issue to\ncause a denial of service. (CVE-2026-47709)\n\nCalvin Young and Enoch Chow discovered that libheif had an integer\noverflow in its inline mask size calculation. An attacker could\npossibly use this issue to cause a denial of service or obtain sensitive\ninformation. (CVE-2026-47714)\n\nAriel Koren discovered that libheif had an integer underflow in its\ngrid image tile coordinate transform. An attacker could possibly use\nthis issue to cause a denial of service or obtain sensitive information.\n(CVE-2026-48029)\n\nIt was discovered that libheif had a missing bound check in its HEIF\nsequence parser, allowing unbounded heap allocation.
