CVE-2019-19232 PUBLISHED

In Sudo through 1.8.29, an attacker with access to a Runas ALL sudoer account can impersonate a nonexistent user by invoking sudo with a numeric uid that is not associated with any user. NOTE: The software maintainer believes that this is not a vulnerability because running a command via sudo as a user not present in the local password database is an intentional feature.

However, this does not change the fact that sudo was behaving as intended, and as documented, in earlier versions
