RHBA-2018:3664 - Bug Fix Advisory

Topic

Updated selinux-policy packages that fix two bugs are now available for Red Hat Enterprise Linux 7.

Description

The selinux-policy packages contain the rules that govern how confined processes run on the system.

This update fixes the following bugs:

• Prior to this update, rules that allow processes labeled with the "nova_t" domain to use Pluggable Authentication Modules (PAM) were missing in the SELinux policy. Consequently, with SELinux in enforcing mode, the installation of the OpenStack Undercloud node failed on starting the "openstack-nova-api" service and SELinux denied also other PAM processes related to "nova_t". With this update, the missing allow rules have been added, and SELinux no longer denies "nova_t" to use PAM. (BZ#1645270)
• Previously, rules that allow the "sysstat_t" domain to read the /var/log/audit/ directory were missing in the SELinux policy. As a consequence, SELinux denied processes while registering a Red Hat Virtualization Host (RHVH) system to the Red Hat Virtualization Manager (RHVM). With this update, the missing rules have been added to the policy, and SELinux denials no longer occur in the described scenario. (BZ#1645271)

Users of selinux-policy are advised to upgrade to these updated packages, which fix these bugs.
