Description Hanno Böck gentoo-dev 2017-06-03 08:26:17 UTC
The fix for CVE-2017-1000367 was incomplete. While it prevents the privilege escalation, it is still possible to trick sudo into writing to other user's terminals.

See update at

=app-admin/sudo-1.8.20_p2 is already in the tree, but not yet stabilized. Can we start stabilizing
