{"id":"UBUNTU-CVE-2026-54627","details":"SAIL is a cross-platform library for loading and saving images with support for animation, metadata, and ICC profiles. In 0.9.10 and earlier, psd_private_sail_pixel_format() in src/sail-codecs/psd/helpers.c resolves a one-channel PSD in Bitmap color mode to SAIL_PIXEL_FORMAT_BPP1_INDEXED without requiring the file depth to be one, so the pixel buffer uses one-bit rows while sail_codec_load_frame_v8_psd() in src/sail-codecs/psd/psd.c accepts depth == 8 and writes one attacker-controlled byte per pixel. Loading a crafted PSD through sail_load_from_file() or sail_load_from_memory() therefore writes beyond each heap row, causing memory corruption, a reliable crash, or potential code execution. This mode/depth mismatch is distinct from GHSA-rcqx-gc76-r9mv and GHSA-wcj8-hxxf-pq2c. This issue is fixed in version 1.0.0.","modified":"2026-09-21T21:38:46.793585883Z","published":"2026-09-21T00:00:00Z","upstream":["CVE-2026-54627"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-54627"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-54627"},{"type":"REPORT","url":"https://github.com/HappySeaFox/sail/security/advisories/GHSA-ccqf-rv86-h3wm"},{"type":"REPORT","url":"https://github.com/HappySeaFox/sail/commit/f44a8b779a1fc527fc6bc5caa71a66a8ed940d50"},{"type":"REPORT","url":"https://github.com/HappySeaFox/sail/commit/f44a8b779a1fc527fc6bc5caa71a66a8ed940d50"},{"type":"REPORT","url":"https://github.com/HappySeaFox/sail/releases/tag/v1.0.0"}],"affected":[{"package":{"name":"sail","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/sail?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.9.0+repack-1","0.9.0+repack-2","0.9.0+repack-2.1","0.9.0+repack-2.1build1"],"ecosystem_specific":{"binaries":[{"binary_name":"libsail-c++0t64","binary_version":"0.9.0+repack-2.1build1"},{"binary_version":"0.9.0+repack-2.1build1","binary_name":"libsail-common0t64"},{"binary_name":"libsail-manip0t64","binary_version":"0.9.0+repack-2.1build1"},{"binary_version":"0.9.0+repack-2.1build1","binary_name":"libsail0t64"},{"binary_name":"sail-codecs","binary_version":"0.9.0+repack-2.1build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-54627.json"}},{"package":{"name":"sail","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/sail?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.9.9-1","0.9.10-1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.9.10-1","binary_name":"libsail-c++0t64"},{"binary_name":"libsail-common0t64","binary_version":"0.9.10-1"},{"binary_name":"libsail-manip0t64","binary_version":"0.9.10-1"},{"binary_name":"libsail0t64","binary_version":"0.9.10-1"},{"binary_name":"sail-codecs","binary_version":"0.9.10-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-54627.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
