NVD Description

Note: Versions mentioned in the description apply only to the upstream libpng package and not the libpng package as distributed by Ubuntu.

In libpng 1.6.34, a wrong calculation of row_factor in the png_check_chunk_length function (pngrutil.c) may trigger an integer overflow and resultant divide-by-zero while processing a crafted PNG file, leading to a denial of service.
