Todd C. Miller reports:

+
When sudo is configured to allow a user to run commands as an + arbitrary user via the ALL keyword in a Runas specification, it + is possible to run commands as root by specifying the user ID -1 + or 4294967295.
+
This can be used by a user with sufficient sudo privileges to + run commands as root even if the Runas specification explicitly + disallows root access as long as the ALL keyword is listed first + in the Runas specification.
+
Log entries for commands run this way will list the target user + as 4294967295 instead of root. In addition, PAM session modules + will not be run for the command.
