Description Patrick Del Bello 2023-03-15 19:27:43 UTC

OpenDoas through 6.8.2, when TIOCSTI is available, allows privilege escalation because of sharing a terminal with the original session. NOTE: TIOCSTI is unavailable in OpenBSD 6.0 and later, and can be made unavailable in the Linux kernel 6.2 and later.
