  "description": "SAIL is a cross-platform library for loading and saving images with support for animation, metadata, and ICC profiles. Prior to commit 36aa5c7ec8a2bb35f6fb867a1177a6f141156b02, the XWD codec resolves pixel format based on \u0060pixmap_depth\u0060 but the byte-swap code uses \u0060bits_per_pixel\u0060 independently. When \u0060pixmap_depth=8\u0060 (BPP8_INDEXED, 1 byte/pixel buffer) but \u0060bits_per_pixel=32\u0060, the byte-swap loop accesses memory as \u0060uint32_t*\u0060, reading/writing 4x the allocated buffer size. This is a different vulnerability from the previously reported GHSA-3g38-x2pj-mv55 (CVE-2026-27168), which addressed \u0060bytes_per_line\u0060 validation. Commit 36aa5c7ec8a2bb35f6fb867a1177a6f141156b02 contains a patch.",
