Notes

Author	Note
mdeslaur	Ubuntu packages are built with BUILD_MJ2:BOOL=OFF, so the affected code isn’t compiled
ccdm94	according to the comments available in issue 1328 of openjpeg (https://github.com/uclouvain/openjpeg/issues/1328), this issue will not be fixed by upstream, as the vulnerable components were simply removed from the code in pull request #1350. For this reason, xenial and trusty cannot be patched for this issue in package openjpeg.
