Background ========== sudo allows a system administrator to give users the ability to run commands as other users. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-admin/sudo < 1.9.12_p2 >= 1.9.12_p2 Description =========== The sudoedit (aka -e) feature mishandles extra arguments passed in the user-provided environment variables (SUDO_EDITOR, VISUAL, and EDITOR), allowing a local attacker to append arbitrary entries to the list of files to process. Impact ====== The improper processing of user's environment variables could lead to the editing of arbitrary files as root, potentially leading to root privilege escalation. Workaround ========== There is no known workaround at this time. Resolution ========== All sudo users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-admin/sudo-1.9.12_p2" References ========== [ 1 ] CVE-2023-22809 https://nvd.nist.gov/vuln/detail/CVE-2023-22809 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/202305-12 Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users' machines is of utmost importance to us.
