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.
Weakness
The product does not handle or incorrectly handles an exceptional condition.
