CVE-2017-6193

This exploit demonstrates a buffer overflow in APNGDis 2.8 via a malformed PNG file with an oversized IHDR chunk descriptor (0xFFFFFFF4). The PoC triggers a heap corruption, leading to a crash (DoS) and potential arbitrary code execution under controlled conditions.

This exploit demonstrates a buffer overflow vulnerability in APNGDis 2.8 by manipulating the width and height fields in a PNG file's IHDR chunk, leading to memory corruption and a segmentation fault. The PoC file triggers invalid memory reads/writes, as confirmed by Valgrind output.
