DLA-3272-1 sudo -- LTS security update
- Date Reported:
- 18 Jan 2023
- Affected Packages:
- 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.

For Debian 10 buster, this problem has been fixed in version 1.8.27-1+deb10u5.
We recommend that you upgrade your sudo packages.
