My previous attempt to fix these bugs did not work. The patch for CVE-2016-7163 was mangled in a confusing way, and the patch for CVE-2016-5157 simply did not apply. Here is an updated patch series. First, it updates openjpeg to 2.1.1, which apparently has not changed the ABI or API: https://github.com/uclouvain/openjpeg/blob/master/NEWS.md#openjpeg-211 Then, it applies the fix for CVE-2016-7163 to openjpeg and openjpeg-2.0. Finally, it adapts the upstream fix for CVE-2016-5157 and applies it to openjpeg. I had to amend this commit slightly, since the diff that adds tests for the fixed issue referred to a commit that is not yet released. Also, the fix for CVE-2016-5157 does not apply to openjpeg-2.0. I'd like to investigate this issue separately. The only user of openjpeg-2.0 is mupdf.
