Package        : sudo
Version        : 1.8.27-1+deb10u5
CVE ID         : CVE-2023-22809


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.
