Debian Security Advisory
DSA-5321-1 sudo -- 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.
Details can be found in the upstream advisory at https://www.sudo.ws/security/advisories/sudoedit_any/ .
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.
