RHBA-2011:0935 - Bug Fix Advisory

Topic

Updated selinux-policy packages that fix various 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:

• Due to a constraint violation, the xinetd daemon was unable to connect to

localhost in the enforcing mode, causing the operation to fail. With this
update, the xinetd daemon is now trusted to write outbound packets regardless of
the network's or node's MLS (Multi-Level Security) range, and the bug no longer
occurs. (BZ#712410)

• Previously, a secadm SELinux user was not allowed to modify SELinux

configuration files. With this update, the relevant SELinux policy has been
fixed, and the secadm SELinux user can now modify these configuration files.
(BZ#712194)

• Previously, the rsyslogd daemon was unable to send messages encrypted with the

TLS (Transport Layer Security) protocol. This bug has been fixed, and rsyslogd
now sends these encrypted messages as expected. (BZ#717688)

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