Red Hat Security Advisory 2014-1906-01

Red Hat Security Advisory 2014-1906-01
Posted Nov 26, 2014
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2014-1906-01 - OpenShift Enterprise by Red Hat is the company's cloud computing Platform-as-a-Service solution designed for on-premise or private cloud deployments. It was found that OpenShift Enterprise 2.1 did not properly restrict access to services running on different gears. This could allow an attacker to access unprotected network resources running in another user's gear. In a previous update, OpenShift Enterprise 2.2 introduced the oo-gear-firewall command, which creates firewall rules and SELinux policy to contain services running on gears to their own internal gear IPs. The command is invoked by default during new installations of OpenShift Enterprise 2.2 to prevent this security issue.

=====================================================================

1. Summary:

Red Hat OpenShift Enterprise release 2.1.9, which fixes two security
issues, several bugs, and add one enhancement, is now available.

Red Hat Product Security has rated this update as having Moderate security
impact. Common Vulnerability Scoring System (CVSS) base scores, which give
detailed severity ratings, are available for each vulnerability from the
CVE links in the References section.

2. Relevant releases/architectures:

RHOSE Infrastructure 2.1 - noarch
RHOSE JBoss EAP add-on 2.1 - noarch
RHOSE Node 2.1 - noarch

3. Description:

OpenShift Enterprise by Red Hat is the company's cloud computing
Platform-as-a-Service (PaaS) solution designed for on-premise or private
cloud deployments.

It was found that OpenShift Enterprise 2.1 did not properly restrict access
to services running on different gears. This could allow an attacker to
access unprotected network resources running in another user's gear.

In a previous update, OpenShift Enterprise 2.2 introduced the
oo-gear-firewall command, which creates firewall rules and SELinux policy
to contain services running on gears to their own internal gear IPs.
The command is invoked by default during new installations of OpenShift
Enterprise 2.2 to prevent this security issue. This update backports the
command to OpenShift Enterprise 2.1.; administrators should run the
following command on node hosts in existing OpenShift Enterprise 2.1
deployments after applying this update to address this security issue:

# oo-gear-firewall -i enable -s enable

Please see the man page of the oo-gear-firewall command for more details.
(CVE-2014-3674)

It was found that OpenShift Enterprise did not restrict access to the
/proc/net/tcp file in gears, which allowed local users to view all
listening connections and connected sockets. This could result in remote
system's IP or port numbers in use to be exposed, which may be useful for
further targeted attacks.

Note that for local listeners, OpenShift Enterprise restricts connections
to within the gear by default, so even with the knowledge of the local port
and IP, the attacker is unable to connect. The SELinux policy on node hosts
has been updated to prevent this gear information from being accessed by
local users.

Due to the closing of this access, JBoss-based cartridges that relied on it
previously must be upgraded according to the standard procedure. This is a
compatible cartridge upgrade and therefore does not require a restart.
(CVE-2014-3602)

Space precludes documenting all of the bug fixes and enhancements in this
advisory. See the OpenShift Enterprise Technical Notes linked to in the
References section, which will be updated shortly for release 2.1.9, for
details about these changes.

All OpenShift Enterprise users are advised to upgrade to these updated
packages.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

See the OpenShift Enterprise 2.1 Release Notes linked to in the References
section, which will be updated shortly for release 2.1.9, for important
instructions on how to fully apply this asynchronous errata update.

This update is available via the Red Hat Network. Details on how to use the
Red Hat Network to apply this update are available at
https://access.redhat.com/site/articles/11258.
