Red Hat Identity Management (IdM) is a centralized authentication, identity
management, and authorization solution for both traditional and cloud-based
enterprise environments.

Security Fix(es):

* It was found that IdM’s ca-del, ca-disable, and ca-enable commands did not
properly check the user’s permissions while modifying CAs in Dogtag. An
authenticated, unauthorized attacker could use this flaw to delete, disable, or
enable CAs causing various denial of service problems with certificate issuance,
OCSP signing, and deletion of secret keys. (CVE-2017-2590)

This issue was discovered by Fraser Tweedale (Red Hat).

Bug Fix(es):

* Previously, during an Identity Management (IdM) replica installation that runs
on domain level “1” or higher, Directory Server was not configured to use TLS
encryption. As a consequence, installing a certificate authority (CA) on that
replica failed. Directory Server is now configured to use TLS encryption during
the replica installation and as a result, the CA installation works as expected.
(BZ#1410760)

* Previously, the Identity Management (IdM) public key infrastructure (PKI)
component was configured to listen on the “::1” IPv6 localhost address. In
environments have the the IPv6 protocol disabled, the replica installer was
unable to retrieve the Directory Server certificate, and the installation
failed. The default listening address of the PKI connector has been updated from
the IP address to “localhost”. As a result, the PKI connector now listens on the
correct addresses in IPv4 and IPv6 environments. (BZ#1416481)

* Previously, when installing a certificate authority (CA) on a replica,
Identity Management (IdM) was unable to provide third-party CA certificates to
the Certificate System CA installer. As a consequence, the installer was unable
to connect to the remote master if the remote master used a third-party server
certificate, and the installation failed. This updates applies a patch and as a
result, installing a CA replica works as expected in the described situation.
(BZ#1415158)

* When installing a replica, the web server service entry is created on the
Identity Management (IdM) master and replicated to all IdM servers. Previously,
when installing a replica without a certificate authority (CA), in certain
situations the service entry was not replicated to the new replica on time, and
the installation failed. The replica installer has been updated and now waits
until the web server service entry is replicated. As a result, the replica
installation no longer fails in the described situation. (BZ#1416488)
