I don't know if it is a security bug or not. When I use sysrc today, the error operations emptied my /etc/rc.conf, that's a small disaster, because my /etc/rc.conf is updated day by day, but now, it is empty.
First, change your default root shell to sh/ksh or their derived shell. (I have tested, csh will not trigger that bug). Second, backup /etc/rc.conf to any other place. Then do the following commands: ------------------------------------------------------------------------ # sysrc something_enable="NO" # sysrc something_enable="YES > " awk: newline in string YES ... at source line 1 something_enable: NO -> YES ------------------------------------------------------------------------ Now see what is inside /etc/rc.conf ? Everything is empty! only one thing in it: ------------------------------------------------------------------------ something_enable="YES " ------------------------------------------------------------------------ Sent with [ProtonMail](https://protonmail.com) Secure Email. _______________________________________________ freebsd-security@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-security To unsubscribe, send any mail to "freebsd-security-unsubscr...@freebsd.org"
