Shawn,

While this fixes the symptom, I think that this is actually a systemd bug as well. Libvirt handles incorrect UID entries correctly.

https://bugzilla.redhat.com/show_bug.cgi?id=1657021

The error handling in the authorization stack probably needs to be analyzed.

On a related note to pkexec, anyone know how to mitigate this?

"Do not allow negative UIDs or UIDs greater than 2147483646."

....... which is weird, since patches were upstream:
- https://gitlab.freedesktop.org/zbyszek/polkit/commit/fbaab32cb4ed9ed5f1e3eea6cd317d443aa427dc
- https://gitlab.freedesktop.org/zbyszek/polkit/commit/7c8c3abdedbb991a69bc5f1ab0f96576958b55de

I'll ask around on the RHEL product security team to see what's up.

If anyone wants to follow along:
https://bugzilla.redhat.com/show_bug.cgi?id=1655925

update: RHEL7 patch currently going through QA and should be released shortly.
