Out of curiosity, which version of the audit package is doing this? And
what C library is aureport linked with?
I think I found it. It should be fixed by this commit:
https://github.com/linux-audit/audit-userspace/commit/
cd06bc803355a535104c057370f7960c11aeef8f
Looks like sudo is sending malformed events. I'll look into that and see if I
can also get that fixed, too.

It looks like we have an unterminated string somewhere. IOW, it's
picked
this up somewhere and you're seeing the effect on output which isn't
helpful. If this is reproducible, can you narrow down the event that is
causing this by altering the start and end times to see if you can get it
down to a couple events? That would be helpful if you can.
Thanks,
