Notes

mdeslaur

Ubuntu packages are built with -DBUILD_JPWL:BOOL=OFF, so the vulnerable code isn't compiled

ccdm94

the openjpeg package does not include the file patched by commit 619e1b086ea. Before the refactoring, there was a single convert.c file, which according to the code, seems to be affected by this vulnerability, however, it seems like the vulnerability in this case is related to CVE-2016-9118 instead, which has a very similar patch.
