In 0.9.10 and earlier, the TGA_INDEXED_RLE path selected by image_type == 9 allocates an image buffer using the one-byte-per-pixel SAIL_PIXEL_FORMAT_BPP8_INDEXED format returned by tga_private_sail_pixel_format() in src/sail-codecs/tga/helpers.c, while sail_codec_load_frame_v8_tga() in src/sail-codecs/tga/tga.c derives a two-to-four-byte pixel_size from an attacker-controlled header bpp value from 9 through 32. Loading a crafted color-mapped run-length-encoded TGA through sail_load_from_file() or sail_load_from_memory() therefore writes attacker-controlled bytes beyond the heap pixel buffer. The pixel-count clamp added for CVE-2026-40494 does not constrain the per-pixel write width, so this issue is an incomplete fix of that vulnerability and can cause heap corruption, a reliable crash, or potential code execution. This issue is fixed in version 1.0.0.","published":"2026-09-17T20:16:51.970","modified":"2026-09-17T20:16:51.970","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/fa24bceb93958ad665dbc3cf6b49a1079ab12559","label":"HappySeaFox/sail@fa24bce"},"references":[{"type":"WEB","url":"https://github.com/HappySeaFox/sail/commit/fa24bceb93958ad665dbc3cf6b49a1079ab12559"},{"type":"WEB","url":"https://github.com/HappySeaFox/sail/releases/tag/v1.0.0"},{"type":"WEB","url":"https://github.com/HappySeaFox/sail/security/advisories/GHSA-744p-cqg2-m33h"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-17T20:16:51.970"}}
