Medium Nessus Plugin ID 119341
SynopsisThe remote Red Hat host is missing one or more security updates.
DescriptionUpdated 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.
