** DISPUTED ** 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. Because this behavior surprised some users, sudo
1.8.30 introduced an option to enable/disable this behavior with the
default being disabled. However, this does not change the fact that sudo
was behaving as intended, and as documented, in earlier versions.
mdeslaurupstream sudo has disputed this CVE, sudo works as intended and
as documented, so marking this as not-affected.
