doas environmental security

Contributed by rueda on from the a-more-su_table-approach dept.

Ted Unangst (tedu@) posted to the tech@ mailing list regarding recent changes to environment handling in doas (in -current):

After some reflection, I've been convinced that it's unlikely everybody reads
the manuals, or that the manuals are even correct or complete. So the new doas
behavior moving forward is to reset most everything to the target user's

Your action items, as we like to say in the biz, are:

1. Check existing configs for "restricted root" rules and verify that they are
run with the correct environment.

2. When updating, check for rules that intentionally use inherited environment
variables. They may need to be explicitly passing using setenv in doas.conf.

Readers are encouraged to read the entire message.
