CVE-2018-20846

Note

Marking emscripten ignored as openjpeg2 code is only for test/example.
Debian binary packages built with BUILD_MJ2:BOOL=OFF
According to https://github.com/uclouvain/openjpeg/pull/1168#commitcomment-32961642 the patch https://github.com/uclouvain/openjpeg/commit/e1740e7ce79d0a1676db4da0f4189b64e85f52cb was reverted because it did not compile. Code is not present in upstream master anymore
Ubuntu packages are built with BUILD_MJ2:BOOL=OFF, so the
affected code isn't compiled
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. There was a patch available, which was commit
c277159986c, however, it did not compile, and therefore was
reverted by upstream. No new fixes for this issue were made
available, the solution apparently being the removal of the code
that contains the vulnerability.
