Description

Jesse Smith of Resonating Media reports:

Previous versions of "doas" transferred most environment variables, such

as USER, HOME, and PATH from the original user to the target user.

Passing these variables could cause files in the wrong path or

home directory to be read (or written to), which resulted in potential

security problems.
