Comment 1 Wolfgang Frisch 2020-12-15 16:01:33 UTC
I did a git bisect and the earliest vulnerable commit is:

commit 84f3bebbff515f2b00ccf0c817930ebb10b91760 (refs/bisect/bad)
Author: Even Rouault <even.rouault@spatialys.com>
Date:   Wed Feb 12 15:55:16 2020 +0100

    Implement writing of IMF profiles

    Add -IMF switch to opj_compress as well
----------------------------------------------------------------------

None of the PoCs triggers a buffer over-read without -IMF.

[1] Not reproducible. No IMF support.
[2] Not reproducible. No IMF support. Upstream patch applies.

Please double-check.

Hi, any update on this?
Comment 4 Gabriele Sonnu 2022-09-16 09:19:14 UTC
We decided to WONTFIX the embedded openjpeg2 in ghostscript, since backporting the patches or compiling it with the system openjpeg2 could likely cause regressions.

@Hans, we are still missing submissions for:

- SUSE:SLE-15:Update/openjpeg2
