RHEL 6 : rubygem-passenger (RHSA-2013:1136)

Medium Nessus Plugin ID 119341

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

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.

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.

Solution

Update the affected packages.
