Security database references:
In Mitre's CVE dictionary: CVE-2023-22809.
More information:

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.

Details can be found in the upstream advisory at .

For the stable distribution (bullseye), this problem has been fixed in version 1.9.5p2-3+deb11u1.

We recommend that you upgrade your sudo packages.
