https://notcve.org/view.php?id=CVE-2018-13785
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. En libpng 1.6.34, un cálculo erróneo de row_factor en la función png_check_chunk_length (pngrutil.c) podría desencadenar un desbordamiento de enteros y una división entre cero resultante al procesar un archivo PNG manipulado, lo que conduciría a una denegación de servicio (DoS). • http://www.oracle.com/technetwork/security-advisory/cpuoct2018-4428296.html http://www.securityfocus.com/bid/105599 http://www.securitytracker.com/id/1041889 https://access.redhat.com/errata/RHSA-2018:3000 https://access.redhat.com/errata/RHSA-2018:3001 https://access.redhat.com/errata/RHSA-2018:3002 https://access.redhat.com/errata/RHSA-2018:3003 https://access.redhat.com/errata/RHSA-2018:3007 https://access.redhat.com/errata/RHSA-2018:3008 https://access.redhat.com/errata/ • CWE-190: Integer Overflow or Wraparound CWE-369: Divide By Zero •
