This violates security assumptions made by pam_shells and some daemons which allow access based on a user's shell being listed in /etc/shells. Under some circumstances, users which had their shell changed to /sbin/nologin could still access the system.","published":"2018-07-03T01:29:01.000Z","lastModified":"2026-06-17T01:50:30.000Z","status":"Modified","sourceIdentifier":"secalert@redhat.com","cvss":{"version":"3.0","score":5.3,"severity":"MEDIUM","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L"},"cwe":["CWE-285","CWE-732"],"affected":["redhat/setup","redhat/enterprise linux desktop","redhat/enterprise linux server","redhat/enterprise linux workstation"],"epss":{"score":0.00315,"percentile":0.2423,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.32%).
