Xerox Security Bulletin XRX18-025

Xerox FreeFlow Print Server 8

Update Manager Delivery of: April 2018 Security Patch Cluster

Includes: Java 6 Update 191

Bulletin Date: June 18, 2018

1.0 Background

Oracle delivers quarterly Critical Patch Updates (CPU) to address 
US-CERT-announced Security vulnerabilities and deliver reliability 
improvements for the Solaris Operating System platform . Oracle does not 
provide these patches to the public , but authorize vendors like Xerox to 
deliver them to Customers with an active FreeFlow Print Server Support 
Contracts (FSMA). Customers who may have an Oracle Support Contract for their
non-FreeFlow Print Server/Solaris Servers should not install patches not 
prepared/delivered by Xerox. Installing non-authorized patches for the 
FreeFlow Print Server software violates Oracle agreements, can render the 
platform inoperable, and result in downtime and/or a lengthy re-installation 
service call.

This bulletin announces the availability of the following:

1. April 2018 Security Patch Cluster 
   o Supersedes the January 2018 Security Patch Cluster
2. Java 6 Update 191 Software
   o Supersedes Java 6 Update 181 Software

CAVEAT: We have a caveat with the April 2018 Security Patch Cluster for the 
FreeFlow Print Server 8.2 software releases. The FreeFlow Print Server 
application is not able to access remote SMB shares after installing the April
2018 Security Patch Cluster. This does not affect the SMB shares used for Hot
Folder workflow. The affected capabilities are SMB access of remote job files
by the 'Print From File' client, and storing PDF/TIFF files to a remote 
location over SMB from a hardcopy scan (E.g., commonly done on a Nuvera 
printer). It is not common for a Security conscience customer to use SMB 
workflows, so this should not affect many customers.

See US-CERT Common Vulnerability Exposures (CVE) the April 2018 Security 
Patch Cluster remediate in table below:

CVE-2017-3169 CVE-2017-7659 CVE-2017-7679 CVE-2018-2563 CVE-2018-2764

CVE-2018-2790 CVE-2018-2795 CVE-2018-2797 CVE-2018-2799 CVE-2018-2814

Note: Xerox recommends that customers evaluate their security needs 
periodically and if they need Security patches to address the above CVE 
issues, schedule an activity with their Xerox Service team to install this 
announced Security Patch Cluster. Alternatively,the customer can install the 
Security Patch Cluster using the Update Manager UI from the Xerox FreeFlow 
Print Server Platform.

2.0 Applicability

Xerox offers the Security Patch Update delivery available over the network 
from a Xerox server using an application called FreeFlow Print Server Update 
Manager. The use of FreeFlow Print Server Update Manager (GUI - based 
application) makes it simple for a customer to install Security patch updates.

The FreeFlow Print Server Update Manager delivery of the Security Patch 
Cluster provides the ability to install Security patches on top of a 
pre-installed FreeFlow Print Server software release. The advantage of this 
network install method is the ease of deliver and install of this network 
delivery from a Xerox patch server over the Internet. This easy install method
provides a FreeFlow Print Server customer the option to manage the quarterly 
Security Patch Cluster instal l without need for support from Xerox service. 
This empowers the customer to have the option of installing these patch 
updates as soon as they become available, and not need to rely on the Xerox 
Service team. Many customers do not want the responsibility of installing the
quarterly Security Patch Update or they are not comfortable providing a 
network tunnel to the Xerox or Microsoft server s that store the Security 
Patch Update. In this case, the media install method (i.e., USB/DVD) is the 
best option under those circumstances.

This Security patch deliverable has been tested on the FreeFlow Print Server 
82.H3.64 software release . We have not tested the April 2018 Security Patch
Cluster on all earlier FreeFlow Print Server 8.2 releases, but there should 
not be any problems on these releases.

A tool is available that enables identification of the currently installed 
FreeFlow Print Server software release, Security Patch Cluster, and Java 
Software version. Run this tool after the Security Patch Cluster install to 
validate successful install. Example output from this script for the FreeFlow
Print Server v8 software release is as following:

FFPS Release Version     8.0-2_SP-2_(82.H3.64.86) 
FFPS Patch Cluster       April 201 8 
Java Version             Java 6 Update 191

The April 2018 Security Patch Cluster is available for the FreeFlow Print 
Server v8 release running on the Xerox printer products below:

1. Xerox iGen 4 Press 
2. Xerox Color 800/1000 Press 
3. Xerox Color 560/570 Printer 
4. Xerox 700 /700i Digital Color Press 
5. Xerox 770 Digital Color Press

Xerox strives to deliver Security Patch Clusters in a timely manner. The 
customer process to obtain Security Patch Cluster updates (delivered on a 
quarterly basis) is to contact the Xerox hotline support number, or use Update
Manager to install as the System Administrator. Update Manager is a GUI tool 
on the FreeFlow Print Server platform used to check for Security patches, 
download Security patches, and install Security patches. The customer can 
install a quarterly Security Patch Cluster using the Update Manager UI, or 
schedule Xerox Service to perform the install.

Once the Security patches are ready for customer delivery, they are available
from the Xerox patch server. Procedures are available for the FreeFlow Print 
Server System Administrator or Xerox Service for using the Update Manager GUI
to download and install the Security patches over the Internet. The Update 
Manager UI has a 'Check for Updates button that can be selected to retrieve 
and list patch updates available from the Xerox patch server. When this option
is selected the latest Security Patch Cluster should be listed (E.g., April 
2018 Security Patch Cluster for FFPS v8.2) as available for download and 
install. The Update Manager UI includes mouse selectable buttons to download 
and then install the patches.

Xerox uploads the Security Patch Cluster to a Xerox patch server that is 
available on the Internet outside of the Xerox Corporate network once the 
deliverable has been tested and approved. Once in place on the Xerox server, a
CSE/Analyst or the customer can use FreeFlow Print Server Update Manager UI to
download and install on the FreeFlow Print Server platform.

The customer proxy information is required to be setup on the FreeFlow Print 
Server platform so it can access to the Security Patch Update over the 
Internet. The FreeFlow Print Server platform initiates a secure communication
session with the Xerox patch server using HTTP over the TSL 1.0 protocol 
(HTTPS on port 443) using an RSA 2018-bit certificate, SHA2 hash and 
AES256-bit stream encryption algorithms. This connection ensures 
authentication of the FreeFlow Print Server platform for the Xerox server, and
sets up encrypted communication of the patch data. The Xerox server does not 
initiate or have access to the FreeFlow Print Server platform behind the 
customer firewall. The Xerox server and FreeFlow Print Server platform both 
authenticate each other before making a connection between the two end-points,
and patch data transfer.
