Severity: important
Tags: security upstream

Hi,

The following vulnerabilities were published for sudo, and adressed
for both in 1.8.30b2[2].

CVE-2019-19232[0]:
| 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.


CVE-2019-19234[1]:
| In Sudo through 1.8.29, the fact that a user has been blocked (e.g.,
| by using the ! character in the shadow file instead of a password
| hash) is not considered, allowing an attacker (who has access to a
| Runas ALL sudoer account) to impersonate any blocked user.


If you fix the vulnerabilities please also make sure to include the
CVE (Common Vulnerabilities & Exposures) ids in your changelog entry.
