https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D231480 Conrad Meyer <cem@freebsd.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Assignee|cem@freebsd.org |ports-bugs@FreeBSD.org --- Comment #5 from Conrad Meyer <cem@freebsd.org> --- The github PR has been merged, so (host) is now read-only and access limite= d to the unprivileged 'nobody' user. That (?)might be sufficient to resolve this bug as-reported, since most secrets will not be readable by user 'nobody'.= =20 That said, the guest should not have arbitrary 'nobody'-level read access to the host filesystem anyway, so it's still a privilege escalation that needs fixed. Adding chroot()+chdir() (both are essential!) in the non-'-r host' case is pretty trivial, if someone wants to tackle that. I can help provide pointe= rs but I think I'm done with grub-bhyve work myself for the time being. --=20 You are receiving this mail because: You are the assignee for the bug.=
