Debian 10 DLA-3272-1 Moderate: Sudo Privilege Escalation Risk

Matthieu Barjole and Victor Cutillas discovered that sudoedit in sudo, a
program designed to provide limited super user privileges to specific
users, does not properly handle '--' to separate the editor and arguments
from files to edit. A local user permitted to edit certain files can take
advantage of this flaw to edit a file not permitted by the security
policy, resulting in privilege escalation.

For Debian 10 buster, this problem has been fixed in version
1.8.27-1+deb10u5.

We recommend that you upgrade your sudo packages.
