Summary
In libpng until version 1.6.35, a wrong calculation of row_factor in the
png_check_chunk_length function (pngrutil.c) may trigger an integer

file, leading to a denial of service. (CVE-2018-13785)
This update fixes it, also providing the current maintenance releases in
the 1.2 and 1.6 stable branches.
