RHBA-2011:1655 - Bug Fix Advisory

Topic

Updated pki-core packages that fix several bugs and add various enhancements are
now available for Red Hat Enterprise Linux 6.

Description

Red Hat Certificate System is an enterprise software system designed to manage
enterprise public key infrastructure (PKI) deployments. PKI Core contains
fundamental packages required by Red Hat Certificate System, which contain the
Certificate Authority (CA) subsystem.

Note: The Certificate Authority component provided by this update is not
intended to be used as a standalone server. It is installed and operates as a
part of the Red Hat Enterprise Identity (IPA).

Bug fixes:

• Configuration of a certificate server failed with the following error: "Unable

to retrieve CA chain: request failed with HTTP status 500". This occurred due to
a race condition between the process reading the /etc/pki-ca/registry.cfg file
and the restart process as registry.cfg was timestamped on startup. registry.cfg
is now left unmodified on startup. (BZ#698796)

• On Red Hat Certificate System 8, the 64-bit pkicreate script was attempting to

use libCryptoki2.so for SafeNet Luna SA and failed to load it as the library did
not exist. The code has been changed and pkicreate on 64-bit platforms now uses
libCryptoki2_64.so. (BZ#728651)

• The pkiremove command removed all instances of the CA (Certification

Authority) type instead of removing only a specific instance. This occurred
because pkiremove removed the registry directory
/etc/sysconfig/pki/[subsystem_type] instead of removing only the registry entry
for the specific instance in the /etc/sysconfig/pki/[type]/ directory. The
command now removes only the respective type instance. (BZ#691076)

• In a NAT (Network Address Translation) environment, authentication of an IPA

machine clone could fail with a NullPointerException on machine setup. This
happened when the clone tried to authenticate itself with a NAT translated IP
address that was different from the IP address previously used for the
authentication. Therefore, the master IPA machine rejected the authentication.
As the machines use a shared key throughout the connection, the IP check was
redundant and has been removed. (BZ#708075)

• PKI provided Apache Tomcat configuration files which set "user:group" to

"pkiuser:pkiuser". Therefore, the /var/log/tomcat6/catalina.out file was also
owned by pkiuser. As the file needs to be owned by Tomcat 6, the TOMCAT_LOG
variable has been added to the configuration files and Tomcat now uses
"tomcat:tomcat" as its "user:group". (BZ#693835)

• The Dogtag subsystem did not detect a replication failure if the replication

failed during clone setup. Therefore, Dogtag kept looking for the root directory
on the directory server and got into an infinite loop as the replication failed
and the root directory was never created. Dogtag now waits for the replication
to finish and the problem no longer occurs. (BZ#726785)

• Due to changes in startup scripts, the PKI SElinux policy was not applied and

tomcat6 instances ran unconfined. The startup scripts now applies the SElinux
policy if enabled and tomcat6 instances now run with the restrictions defined in
the policy. (BZ#700522)

Enhancements:

• The default validity period of the default and constraint server certificates

has been changed to 2 years. (BZ#729126)

• The number of restarts needed during installation of Dogtag Certicate Server

was decreased. (BZ#689891)

• Several checks have been added to speed up installation of Dogtag Certificate

Server. (BZ#689909)

• The client usage flag has been added to the caIPAserviceCert server

certificate. This allows an IPA server to use the server certificate as a client
certificate and authenticate itself. (BZ#722634)

• The pki-setup-proxy script that adds a configuration file to Apache Tomcat,

updates the server.xml and CS.cfg files has been added. The script upgrades the
proxy configuration of an existing IPA installation to the AJP (Apache JServ
Protocol) proxy code introduced in upstream version 2.1.1. (BZ#737179)

Users should upgrade to these updated pki-core packages, which fix the bugs and
add the enhancements.
