CVE-2018-16375

An issue was discovered in OpenJPEG 2.3.0. Missing checks for header_info.height and header_info.width in the function pnmtoimage in bin/jpwl/convert.c can lead to a heap-based buffer overflow.

These are all security issues fixed in the libopenjp2-7-2.4.0-1.4 package on the GA media of openSUSE Tumbleweed.
