In stable these are not enabled. Though I agree that these issues are pretty bad, we usually treat the console as something that only trusted people can access. As far as I know, there isn't a way to print arbitrary, unescaped data on one of vt(4)'s windows without having a local login session. Earlier this year we wrote an erratum for something similar: a bad ioctl() call on vt(4) that could cause the system to crash. https://www.freebsd.org/security/advisories/FreeBSD-EN-15:01.vt.asc -- You are receiving this mail because: You are the assignee for the bug.
