{"id":"UBUNTU-CVE-2026-62289","details":"libheif is a HEIF and AVIF file format decoder and encoder. In 1.23.0 and earlier, a crafted HEIF or AVIF file containing a clean aperture box can reduce an image dimension to zero and crash or corrupt tiling results when heif_image_handle_get_image_tiling(handle, 1, &tiling) is called. ImageItem::get_heif_image_tiling() returns already transformed dimensions, and process_image_transformations_on_tiling() applies the clean aperture transformation again. The second application passes zero to Box_clap::left_rounded(0), where image_width minus one underflows and constructs Fraction(0xFFFFFFFF, 2). Debug builds reach an assertion and abort, while release builds can return a corrupt crop and zero-width tiling result. The affected implementation spans libheif/image-items/image_item.cc, libheif/context.cc, and libheif/box.cc. This issue is fixed in version 1.23.1.","modified":"2026-09-02T19:36:26.657193799Z","published":"2026-08-13T00:00:00Z","related":["USN-8649-1","USN-8683-1"],"upstream":["CVE-2026-62289"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-62289"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-62289"},{"type":"REPORT","url":"https://github.com/strukturag/libheif/security/advisories/GHSA-jc8f-p23p-5hjg"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-8649-1"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-8683-1"}],"affected":[{"package":{"name":"libheif","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/libheif?arch=source&distro=esm-apps%2Fbionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.1.0-2ubuntu0.1~esm4"}]}],"versions":["1.1.0-2","1.1.0-2ubuntu0.1~esm1","1.1.0-2ubuntu0.1~esm2","1.1.0-2ubuntu0.1~esm3"],"ecosystem_specific":{"availability":"Available
