Broken DNS after installing security update 2019-007

After installing the 2019-007 security update using dosdude1's High Sierra patcher, I found that DNS is broken ... unless I use TCP. For example, this will time out (no response):

dig @8.8.8.8 google.com

But this works fine:

dig +tcp @8.8.8.8 google.com

That's pretty weird! Otherwise, my internet connection seems to be fine -- I can ping all the usual web sites, and open them in a browser if I know the IP address.

Maybe this was just a coincidence, and the DNS breakage has nothing to do with the security update. Has anyone else out there had a similar experience?

Who knows with that piece of garbage. I installed it to have no chance of my machine going 24 hours without a random reboot. It worked flawless before it and after upgrading to Mojave, to check if that fixed it.
