Created oggvideotools tracking bugs for this issue:

Affects: fedora-38 [bug 2234724]

Comment 2 Zbigniew Jędrzejewski-Szmek 2023-08-27 12:51:25 UTC

I suspect that fixing #2234728 will fix this one too.
Unfortunately the original bug reporter forgot to attach the sample.
But the same codepath seems to be triggerred.
