This could allow a user with sufficient sudo privileges to run commands as root even if the Runas specification explicitly disallows root access. Details can be found in the upstream advisory at https://www.sudo.ws/alerts/minus_1_uid.html . For the oldstable distribution (stretch), this problem has been fixed in version 1.8.19p1-2.1+deb9u1. For the stable distribution (buster), this problem has been fixed in version 1.8.27-1+deb10u1. We recommend that you upgrade your sudo packages.
