DEBIAN-CVE-2026-54627

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, psdprivatesailpixelformat() in src/sail-codecs/psd/helpers.c resolves a one-channel PSD in Bitmap color mode to SAILPIXELFORMATBPP1INDEXED without requiring the file depth to be one, so the pixel buffer uses one-bit rows while sailcodecloadframev8psd() in src/sail-codecs/psd/psd.c accepts depth == 8 and writes one attacker-controlled byte per pixel. Loading a crafted PSD through sailloadfromfile() or sailloadfrom_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.
