Details

A useful tool for reducing the scope of security bugs would be to do fewer things as root. As suggested in https://lists.archlinux.org/pipermail/pacman-dev/2020-February/024030.html

For example if the internal downloader and XferCommand were to operate as a separate user e.g. "libalpm", which had write permissions for only /var/cache/pacman/pkg, the following bug would not have been able to write anywhere on the system, and would usually fail with a permission denied error:

The command injections in these bugs could similarly have avoided being able to run command injection *as root*, greatly reducing the scope of the damage they could do:
