Robert Watson <rwat...@freebsd.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |rwat...@freebsd.org --- Comment #8 from Robert Watson <rwat...@freebsd.org> --- A appreciate the desirability for the features implied by this change, but given the propensity for vulnerabilities relating to chroot() in the past, think we should take a very conservative approach to potentially adopting it. There's a particular concern with how it interacts with non-UNIX-ID-based models -- e.g., MAC, Capsicum, Audit, Jail, as well as a future fine-grained privilege model. Overall, I'd rate this proposed change as "extremely high risk; we will fix multiple vulnerabilities in it in the future," and so that cost would need to be carefully weighed against presumed benefit -- a fine-grained privilege model in which PRIV_CHROOT is delegable to only specific users or roles would help mitigate that risk. I wonder if a more suitable name for the proposed P_NOSUGID would be P_NOCREDCHANGE, and I also wonder if it should be CR_NOCREDCHANGE. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ freebsd-bugs@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"
