CVE-2022-43289Public exploit

Process crash via out-of-bounds palette read

Published Dec 19, 2022 · Updated Apr 17, 2025

Out-of-bounds read in Deark 1.6.2 allows local users to crash the utility via a crafted Prism Paint image that a user processes. In do_prism_read_palette at modules/atari-img.c:331, palette processing reads four bytes beyond the stack-allocated pal1 buffer. Exploitation requires a user to run Deark on the crafted file; the published AddressSanitizer trace demonstrates a process crash, not code execution.
