Scientific Linux Security Update : ipa on SL6.x i386/x86_64 (20150722)

medium Nessus Plugin ID 85197

Language:

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

Note: The IdM version provided by this update no longer uses jQuery.

Bug fixes :

 - The ipa-server-install, ipa-replica-install, and ipa-client-install utilities are not supported on machines running in FIPS-140 mode. Previously, IdM did not warn users about this. Now, IdM does not allow running the utilities in FIPS-140 mode, and displays an explanatory message.

 - If an Active Directory (AD) server was specified or discovered automatically when running the ipa-client-install utility, the utility produced a traceback instead of informing the user that an IdM server is expected in this situation. Now, ipa-client-install detects the AD server and fails with an explanatory message.

 - When IdM servers were configured to require the TLS protocol version 1.1 (TLSv1.1) or later in the httpd server, the ipa utility failed. With this update, running ipa works as expected with TLSv1.1 or later.

 - In certain high-load environments, the Kerberos authentication step of the IdM client installer can fail. Previously, the entire client installation failed in this situation. This update modifies ipa-client- install to prefer the TCP protocol over the UDP protocol and to retry the authentication attempt in case of failure.

 - If ipa-client-install updated or created the /etc/nsswitch.conf file, the sudo utility could terminate unexpectedly with a segmentation fault. Now, ipa-client-install puts a new line character at the end of nsswitch.conf if it modifies the last line of the file, fixing this bug.

 - The ipa-client-automount utility failed with the 'UNWILLING_TO_PERFORM' LDAP error when the nsslapd-minssf Red Hat Directory Server configuration parameter was set to '1'. This update modifies ipa-client-automount to use encrypted connection for LDAP searches by default, and the utility now finishes successfully even with nsslapd-minssf specified.

 - If installing an IdM server failed after the Certificate Authority (CA) installation, the 'ipa-server-install
 --uninstall' command did not perform a proper cleanup.
 After the user issued 'ipa-server-install --uninstall' and then attempted to install the server again, the installation failed. Now, 'ipa-server-install
 --uninstall' removes the CA-related files in the described situation, and ipa-server-install no longer fails with the mentioned error message.

 - Running ipa-client-install added the 'sss' entry to the sudoers line in nsswitch.conf even if 'sss' was already configured and the entry was present in the file.
 Duplicate 'sss' then caused sudo to become unresponsive.
 Now, ipa-client-install no longer adds 'sss' if it is already present in nsswitch.conf.

 - After running ipa-client-install, it was not possible to log in using SSH under certain circumstances. Now, ipa-client-install no longer corrupts the sshd_config file, and the sshd service can start as expected, and logging in using SSH works in the described situation.

 - An incorrect definition of the dc attribute in the /usr/share/ipa/05rfc2247.ldif file caused bogus error messages to be returned during migration. The attribute has been fixed, but the bug persists if the copy-schema-to-ca.py script was run on Scientific Linux 6.6 prior to running it on Scientific Linux 6.7. To work around this problem, manually copy /usr/share/ipa/schema/05rfc2247.ldif to /etc/dirsrv /slapd-PKI-IPA/schema/ and restart IdM.

Solution
