Todd Miller reports:

+
Beginning with sudo version 1.7.0 it has been possible to grant + permission to run a command using a specified group via sudo -g + option (run as group). A flaw exists in the logic that matches + Runas groups in the sudoers file when the -u option is also + specified (run as user). This flaw results in a positive match for + the user specified via -u so long as the group specified via -g + is allowed by the sudoers file.
+
Exploitation of the flaw requires that Sudo be configured with + sudoers entries that contain a Runas group. Entries that do not + contain a Runas group, or only contain a Runas user are not + affected.
