An issue was discovered in TrouSerS through 0.3.14. If the tcsd daemon is
started with root privileges, the tss user still has read and write access
to the /etc/tcsd.conf file (which contains various settings related to this
daemon).
Bugs
Notes
| Author | Note |
|---|---|
| mdeslaur | the Debian/Ubuntu package starts tcsd as the tss user, not as root, so this issue doesn’t affect default configurations |
