Red Hat Security Advisory

 

Synopsis: Important: Red Hat OpenShift Enterprise 3.2 security update and bug fix update

Advisory ID: RHSA-2016:1853-01

Product: Red Hat OpenShift Enterprise

Advisory URL: https://access.redhat.com/errata/RHSA-2016:1853

Issue date: 2016-09-12

CVE Names: CVE-2016-5418

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

 

1. Summary:

 

An update for atomic-openshift and heapster is now available for Red Hat

OpenShift Enterprise 3.2.

 

Red Hat Product Security has rated this update as having a security impact

of Important. A Common Vulnerability Scoring System (CVSS) base score,

which gives a detailed severity rating, is available for each vulnerability

from the CVE link(s) in the References section.

 

2. Relevant releases/architectures:

 

Red Hat OpenShift Enterprise 3.2 - noarch, x86_64

 

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.

 

Security Fix(es):

 

* When processing an archive file that contains an archive entry with type

1 (hardlink) but also having a non-zero data size a file overwrite can

occur. This would allow an attacker that can pass data to an application

that uses libarchive to unpack it to overwrite arbitrary files with

arbitrary data. (CVE-2016-5418)

 

Red Hat would like to thank Insomnia Security for reporting this issue.

 

This update also fixes the following bugs:

 

* Previously, pods that had a resource request of 0 and specified limits

were classified as BestEffort when they should have been classified as

Burstable. This bug fix ensures that those pods are correctly classified as

Burstable.(BZ#1357475)

 

* Future versions of docker will require containerized installations of

OpenShift Container Platform to mount /var/lib/origin with the `rslave`

flag. New installations of OpenShift Container Platform 3.2 have this value

set. However, upgrades from 3.1 did not properly set this value. This bug

fix ensures that this flag is now set during upgrades, ensuring that

OpenShift Container Platform works properly under future versions of

docker. (BZ#1358197)

 

* The PersistentVolumeLabel admission plug-in is now enabled by default.

This plug-in labels AWS and GCE volumes with their zone so the scheduler

can limit the nodes for a pod to only those in the same zone as the

persistent volumes being used by the pod. (BZ#1365600)

 

* Previously, heapster incorrectly generated error messages indicating that

it "Failed to find node". This bug fix corrects that error and ensures that

erroneous warnings are generated.(BZ#1366367)

 

* The deployment controllers' resync interval can now be configured. The

previously hard-coded 2-minute default is the likely cause of performance

regressions when thousands of deploymentconfigs are present in the system.

Increase the resync interval by setting deploymentControllerResyncMinute in

/etc/origin/master/master-config.yaml.(BZ#1366381)

 

* Previously, AWS-related environment variables were removed from

/etc/sysconfig/atomic-openshift-master files during an upgrade if these

values were not included in the advanced installer's inventory file. This

bug fix ensures that these variables are now preserved during upgrades.

(BZ#1370641)

 

* Previously, updates to the containerized atomic-openshift-node service

were not properly reloaded during upgrades. This bug fix corrects this

error and ensures that the service is reloaded during upgrades.

(BZ#1371708)

 

* Previously the installer did not properly configure an environment for

flannel when openshift_use_flannel was set to `true`. This bug fix corrects

those errors and the installer will now correctly deploy environments using

flannel. (BZ#1372026)
