Background ========== sudo (su adoa) allows a system administrator to delegate authority to give certain users (or groups of users) the ability to run some (or all) commands as root or another user while providing an audit trail of the commands and their arguments. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-admin/sudo < 1.8.20_p2 >= 1.8.20_p2 Description =========== The fix present in app-admin/sudo-1.8.20_p1 (GLSA 201705-15) was incomplete as it did not address the problem of a command with a newline in the name. Impact ====== A local attacker could execute arbitrary code with root privileges. 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-1.8.20_p2" References ========== [ 1 ] CVE-2017-1000368 https://nvd.nist.gov/nvd.cfm?cvename=CVE-2017-1000368 [ 2 ] GLSA 201705-15 https://security.gentoo.org/glsa/201705-15 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/201710-04 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.
