In Sudo before 1.8.28, an attacker with access to a Runas ALL sudoer
account can bypass certain policy blacklists and session PAM modules,
and can cause incorrect logging, by invoking sudo with a crafted user
ID. For example, this allows bypass of !root configuration, and USER=
logging, for a "sudo -u \#$((0xffffffff))" command.
