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

1. Summary:

An updated rubygem-openshift-origin-node package that fixes one security
issue and several bugs is now available for Red Hat OpenShift Enterprise 
2.1.1.

The Red Hat Security Response Team has rated this update as having Critical
security impact. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available from the CVE link in
the References section.

2. Relevant releases/architectures:

RHOSE Node 2.1 - noarch

3. Description:

The rubygem-openshift-origin-node package provides basic OpenShift node
functionality.

A command injection flaw was found in rubygem-openshift-origin-node.
A remote, authenticated user permitted to install cartridges via the web
interface could use this flaw to execute arbitrary code with root
privileges on the Red Hat OpenShift Enterprise node server. (CVE-2014-3496)

This issue was discovered by Jeremy Choi of the Red Hat HSS Pen-test Team.

The rubygem-openshift-origin-node package has been upgraded to version
1.23.9.11. Additionally, the rubygem-openshift-origin-container-selinux
package has been upgraded to version 0.8.1.2, as needed by the updated
rubygem-openshift-origin-node package.

This update also fixes the following bugs:

* The syslog_logger.rb implementation on nodes made incorrect use of the 
Ruby Syslog library. Raw log message input was handled as a Syslog format 
string, causing failures for many application operations. This bug fix 
updates the implementation to correctly handle raw log message input, and 
the failures no longer occur. (BZ#1096900)

* Under certain conditions, it was possible for the MCollective agent on 
nodes to fail to fully initialize while checking the status of a cartridge.
This resulted in sporadic failures of rhc cartridge status. This bug fix 
ensures that the agent is always fully initialized. (BZ#1102399)

* Developers encountered syntax errors when connecting to a gear using the
'rhc ssh' command if the gear was hosted on a node with quotas disabled.
This was due to the command trying to report quota information but being
given an empty string because quotas were disabled. This bug fix updates
the handling for reporting on quotas when there is no information to
report, and the syntax errors no longer occur. (BZ#1107801)

* If a file containing invalid special characters was placed in an
application's ~/.env/user_vars directory, subsequent interactions with the
application using SSH or Git were refused. This was due to problems with
the node component handling the invalid characters. This bug fix updates
the node component to handle problematic files in ~/.env/user_vars; as a
result, interactions with the application using SSH or Git succeed as
normal. (BZ#1096833)

All rubygem-openshift-origin-node users are advised to upgrade to this
updated package, which contains a backported patch to correct this issue.

4. Solution:

5. Bugs fixed (https://bugzilla.redhat.com/):

1096833 - Errors in user_vars/* files block ssh access, git access
1096900 - Log messages are being interpolated by syslog_logger.rb, causing random app operation failures
1102399 - [new relic] undefined method `run_in_container_context' for nil:NilClass on INT nodes
1107801 - rhcsh quota check prints error messages on login if quotas are disabled
1110470 - CVE-2014-3496 OpenShift Origin: Command execution as root via downloadable cartridge source-url
