Inspired by the patch in the debian package.

Comment 3 James Fehlig 2023-07-07 21:51:17 UTC

I've submitted updated packages containing the above patch to the OBS devel project (sr#1097635) and SLE-15:Update (mr#302858). Does that ALP project also need a submission?

Comment 6 James Fehlig 2023-07-13 16:17:52 UTC

SR#303134 sent for ALP. I think that's all for me. Passing to the security team...
