{"id":"CVE-2026-54627","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-54627","summary":"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.","published":"2026-09-17T20:16:52.117","modified":"2026-09-17T20:16:52.117","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/HappySeaFox/sail/commit/f44a8b779a1fc527fc6bc5caa71a66a8ed940d50","label":"HappySeaFox/sail@f44a8b7"},"references":[{"type":"WEB","url":"https://github.com/HappySeaFox/sail/commit/f44a8b779a1fc527fc6bc5caa71a66a8ed940d50"},{"type":"WEB","url":"https://github.com/HappySeaFox/sail/releases/tag/v1.0.0"},{"type":"WEB","url":"https://github.com/HappySeaFox/sail/security/advisories/GHSA-ccqf-rv86-h3wm"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-17T20:16:52.117"}}
