RHBA-2011:1779 - Bug Fix Advisory

Topic

Updated selinux-policy packages that fix three bugs are now available for Red
Hat Enterprise Linux 6.

Description

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

This update fixes the following bugs:

• Users cron jobs were set to run in the cronjob_t domain when the SELinux MLS

policy was enabled. As a consequence, users could not run their cron jobs. With
this update, the relevant policy rules have been modified and users cron jobs
now run in a user domain. (BZ#754112)

• When the auditd daemon was listening on port 60, the SELinux Multi-Level

Security (MLS) policy prevented auditd from sending audit events to itself from
the same system it was running on over port 61, which is possible when using the
audisp-remote plugin. This update fixes the relevant policy so that this
configuration now works as expected. (BZ#754465)

• When running the libvirt commands, such as "virsh iface-start" or "virsh

iface-destroy" in SELinux enforcing mode and NetworkManager was enabled, the
commands took a noticeably long time to finish successfully. With this update,
the relevant policy has been added and libvirt commands now work as expected.
(BZ#754802)

All users of selinux-policy are advised to upgrade to these updated packages,
which resolve these issues.

Solution

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
