CVE-2024-41437Public exploit

Application crash via out-of-bounds PNG read

Published Jul 30, 2024 · Updated Mar 13, 2025

Heap-based buffer overflow in hicolor 0.5.0 allows attackers to crash the application by processing a crafted PNG file. The cp_unfilter function in vendor/cute_png.h reads one byte immediately past a heap allocation while loading PNG data. User interaction is required to process the file, and the demonstrated consequence is an AddressSanitizer abort rather than data disclosure or modification.
