CVE-2018-1113: Red Hat Enterprise Linux Desktop

Medium severity, CVSS 5.3. EPSS: 0.3% chance of exploitation in the next 30 days.

setup before version 2.11.4-1.fc28 in Fedora and Red Hat Enterprise Linux added /sbin/nologin and /usr/sbin/nologin to /etc/shells. 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.

Affected products

• Red Hat Enterprise Linux Desktop: version 7.0 only
• Red Hat Enterprise Linux Server: version 7.0 only
• Red Hat Enterprise Linux Workstation: version 7.0 only
• Red Hat Setup: before 2.11.4 (fixed in 2.11.4)
