✅ Remediation

To fully resolve this problem, you need to manually perform the following steps after installing the updated packages: Disclaimer: The following procedure performs critical, low-level operations on your IPA system, and it is imperative that you back up your system before carrying out any of the following steps. A failure during this procedure may compromise the readability of all or part of your Kerberos keys. 1. Upgrade all of your servers (masters and replicas) and restart the dirsrv service on all of them. No other daemon needs to be restarted at this stage. 2. On one master server, run the following tool: $ ipa-fix-2008-3274 --check This should report that the system is vulnerable. 3. On the same master server, run the following tool: $ ipa-fix-2008-3274 --fix This should dump all Kerberos principals, reload them, and then return a message stating that the operation completed successfully. If not, you should contact Red Hat GSS for immediate assistance. This step should also create a .gpg file symmetrically-encrypted with the Directory Manager password. This file contains a backup of all Kerberos key material and is written to /var/lib/ipa/. Attention: DO NOT RUN THIS COMMAND ON ANY OTHER SERVER. See the next step. 4. On all other IPA servers, run the following tool: $ ipa-fix-2008-3274 --fix-replica This will report that the system is NOT vulnerable and will then download the master key for the local KDC instance. This command will restart the KDC service. If the command reports a system as anything other than not vulnerable, verify that replication between masters is working correctly. The procedure will not successfully complete until replication failures are addressed. Before applying this update, make sure that all previously-released errata relevant to your system have been applied. This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/FAQ_58_10188
