Red Hat Security Advisory

 

Synopsis: Moderate: rubygem-passenger security update

Advisory ID: RHSA-2013:1136-01

Product: Red Hat OpenShift Enterprise

Advisory URL: https://rhn.redhat.com/errata/RHSA-2013-1136.html

Issue date: 2013-08-05

CVE Names: CVE-2013-2119 CVE-2013-4136

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

 

1. Summary:

 

Updated rubygem-passenger packages that fix two security issues are now

available for Red Hat OpenShift Enterprise 1.2.2.

 

The Red Hat Security Response Team 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, x86_64

RHOSE Node 1.2 - noarch, x86_64

 

3. Description:

 

rubygem-passenger is a web server for Ruby, Python and Node.js

applications.

 

The rubygem-passenger gem created and re-used temporary directories and

files in an insecure fashion. A local attacker could use these flaws to

conduct a denial of service attack, take over the operation of the

application or, potentially, execute arbitrary code with the privileges of

the user running rubygem-passenger. (CVE-2013-2119, CVE-2013-4136)

 

Note: By default, OpenShift Enterprise uses polyinstantiation (per user)

for the /tmp/ directory, thereby minimizing the risk and impact of

exploitation by local attackers of both CVE-2013-2119 and CVE-2013-4136.

 

The CVE-2013-2119 issue was discovered by Michael Scherer of the Red Hat

Regional IT team.

 

The following packages are included with this update as dependencies of the

updated Ruby 1.8 passenger packages:

 

rubygem-spruz-0.2.5-4.el6op

rubygem-file-tail-1.0.5-4.el6op

 

Users of Red Hat OpenShift Enterprise 1.2.2 are advised to upgrade to

these updated packages, which correct these issues. After installing the

updated packages, manual action is required before the update takes effect.

Refer to the Solution section for details.

 

4. Solution:

 

Before applying this update, make sure all previously released errata

relevant to your system have been applied.

 

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

 

Manual action is required for this update to take effect. In order for the

updated passenger packages to be loaded by Ruby applications in the PaaS,

the applications must be restarted with oo-admin-ctl-gears. One way to

accomplish this is by running the following command, as a single line

without the line break, on all OpenShift Nodes:

 

for rubyapp in `ls -d /var/lib/openshift/*/ruby |

cut -f5 -d/`; do oo-admin-ctl-gears restartgear $rubyapp; done

 

If there are no Ruby applications on a Node it will simply fail with the

message "No such file or directory". Another option is to run the

following on all OpenShift Nodes; however, it will result in non-Ruby

applications also being restarted:

 

oo-admin-ctl-gears restartall

 

(Note that without the manual action, if a user attempts to restart their

Ruby application via the rhc command line, it will fail to start with a

"Passenger could not be initialized..." error.)

 

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

 

892813 - CVE-2013-2119 rubygem-passenger: incorrect temporary file usage

985633 - CVE-2013-4136 rubygem-passenger: insecure temporary directory usage due to reuse of existing server instance directories
