In version 1.8.0, three inter-frame chunk discard paths in the push-mode APNG parser clear the chunk-header flag without consuming the chunk body and CRC, allowing attacker-controlled bytes inside an ignored ancillary chunk to be reinterpreted as a fresh chunk header on the next call to `png_process_data`. Commit faf06924688b62d7c1654b5ceddedbde66ffadb4 fixes the issue.</p> <p><strong>Affected:</strong> pnggroup libpng, pnggroup libpng-apng</p> <p>LIBPNG is a reference library for use in applications that process PNG (Portable Network Graphics) raster image files.
