it seems like the official patch for this issue is the one in
commit f053508f6, however, in openjpeg xenial seems to not be
vulnerable because another patch has been applied to it, the
one available at https://github.com/uclouvain/openjpeg/files/
478630/openjpeg-nullptr-github-issue-842.ppm-dif.txt.
