MiracleLinux 7 : realmd-0.16.1-5.el7 (AXSA:2015-654:01)

critical Nessus Plugin ID 289597

Synopsis

The remote MiracleLinux host is missing a security update.

Description

The remote MiracleLinux 7 host has a package installed that is affected by a vulnerability as referenced in the AXSA:2015-654:01 advisory.

 realmd is a DBus system service which manages discovery and enrollment in realms and domains like Active Directory or IPA. The control center uses realmd as the back end to 'join' a domain simply and automatically configure things correctly.
 Security issues fixed with this release:
 CVE-2015-2704 realmd allows remote attackers to inject arbitrary configurations in to sssd.conf and smb.conf via a newline character in an LDAP response.
 Fixed bugs:
 * Joining a Red Hat Enterprise Linux machine to a domain using the realm utility creates /home/domainname/[username]/ directories for domain users. Previously, SELinux labeled the domain users' directories incorrectly. As a consequence, the domain users sometimes experienced problems with SELinux policy. This update modifies the realmd service default behavior so that the domain users' directories are compatible with the standard SELinux policy.
 * Previously, the realm utility was unable to join or discover domains with domain names containing underscore (_). The realmd service has been modified to process underscores in domain names correctly, which fixes the described bug.
 Enhancements:
 * The realmd utility now allows the user to disable automatic ID mapping from the command line. To disable the mapping, pass the --automatic-id-mapping=no option to the realmd utility.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected realmd package.
