CVE-2024-46259Public exploit

Application crash via out-of-bounds PNG read

Published Oct 1, 2024 · Updated Mar 18, 2025

Heap buffer overflow in Randy Gaul cute_png 1.05 allows context-dependent attackers to crash applications via a crafted PNG file. During cp_load_png_mem processing, cp_unfilter reads one byte beyond its heap buffer while reconstructing filtered pixel data. A host application must process the attacker-supplied image; the published proof of concept demonstrates an AddressSanitizer-detected abort rather than code execution.
