SAIL vulnerabilities

In SAIL before version 1.0.0, sail_codec_load_frame_v8_xbm() in src/sail-codecs/xbm/xbm.c allocates the decoded pixel buffer using the X11 one-byte-per-literal layout, but an X10 static short file causes the flat decode loop to write two file-controlled bytes per literal. When ceil(width/8) produces an odd row stride, the X10 literal count includes a padding byte for every row that the destination buffer cannot hold, resulting in a forward heap overwrite that scales with image height. The issue is fixed in version 1.0.0.

SAIL library version 0.9.10 and earlier contains a mode/depth mismatch when loading Bitmap-mode PSD files. psd_private_sail_pixel_format() returns a one-bit format while the loader accepts depth 8, causing out-of-bounds heap writes that lead to memory corruption, crashes, or potential code execution.

SAIL library version 0.9.10 and earlier contains an incomplete fix for CVE-2026-40494 in the TGA_INDEXED_RLE path. The image buffer is allocated as one byte per pixel, but the loader derives a wider pixel size from an attacker-controlled bpp value, leading to out-of-bounds heap writes and memory corruption.
