Host process interruption via out-of-bounds PNG read
Published Oct 1, 2024 · Updated Mar 14, 2025
Heap buffer over-read in Randy Gaul cute_png 1.05 allows attackers to access memory beyond a heap allocation via a crafted PNG image. The cp_load_png_mem function reads one byte immediately beyond a 25-byte heap region while parsing the malformed input. An application must pass attacker-controlled PNG data to the embedded library; the demonstrated consequence is an AddressSanitizer process abort.
