- ------------------------------------------------------------------------- Debian LTS Advisory DLA-3272-1 [email protected] https://www.debian.org/lts/security/ Thorsten Alteholz January 18, 2023 https://wiki.debian.org/LTS
- -------------------------------------------------------------------------

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.

https://www.sudo.ws/security/advisories/sudoedit_any/

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

We recommend that you upgrade your sudo packages.

For the detailed security status of sudo please refer to its security tracker page at:
