CVE-2026-54627 · SAIL: Heap out-of-bounds write in SAIL PSD decoder (Bitmap mode ignores depth)

Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.

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.
