What were you trying to do that didn't work?

The CVE-2023-50387 related change in bind required a rebuild of dhcp, and therefore some version combinarions are no longer compatible and able to work together (would or could crash or won't start at all).

The dhcp package should introduce a conflict in the spec file to prevent installing itself with incompatible bind.

Similar changes are being done in bind.

It's not an ideal fix, would only work with updated packages, may not work correctly when updating minor version, but the conflict could prevent at least some incidents.

Having this committed and ready to be shipped with upcoming fixes would be great. I don't think we have to do erratas just for this one.

Please provide the package NVR for which bug is seen:

All latest in streams supported/depending on bind-external-libs.

How reproducible:

Always

Steps to reproduce

1. Downgrade bind and/or dhcp
2. Should downgrade bind as well as dhcp
3. Upgrade dhcp and/or bind
4. Should upgrade bind as well as dhcp.
