RHSA-2013:0582: Moderate: Red Hat OpenShift Enterprise 1.1.1 update

OpenShift Enterprise is a cloud computing Platform-as-a-Service (PaaS)solution from Red Hat, and is designed for on-premise or private clouddeployments.Installing the updated packages and restarting the OpenShift services arethe only requirements for this update. However, if you are updating yoursystem to Red Hat Enterprise Linux 6.4 while applying OpenShift Enterprise1.1.1 updates, it is recommended that you restart your system.For further information about this release, refer to the OpenShiftEnterprise 1.1.1 Technical Notes, available shortly fromhttps://access.redhat.com/knowledge/docs/ This update also fixes the following security issues:Multiple cross-site scripting (XSS) flaws were found in rubygem-actionpack.A remote attacker could use these flaws to conduct XSS attacks againstusers of an application using rubygem-actionpack. (CVE-2012-3463,CVE-2012-3464, CVE-2012-3465)It was found that certain methods did not sanitize file names beforepassing them to lower layer routines in Ruby. If a Ruby application createdfiles with names based on untrusted input, it could result in the creationof files with different names than expected. (CVE-2012-4522)A denial of service flaw was found in the implementation of associativearrays (hashes) in Ruby. An attacker able to supply a large number ofinputs to a Ruby application (such as HTTP POST request parameters sent toa web application) that are used as keys when inserting data into an arraycould trigger multiple hash function collisions, making array operationstake an excessive amount of CPU time. To mitigate this issue, a new, morecollision resistant algorithm has been used to reduce the chance of anattacker successfully causing intentional collisions. (CVE-2012-5371)Input validation vulnerabilities were discovered in rubygem-activerecord.A remote attacker could possibly use these flaws to perform an SQLinjection attack against an application using rubygem-activerecord.(CVE-2012-2661, CVE-2012-2695, CVE-2013-0155)Input validation vulnerabilities were discovered in rubygem-actionpack. Aremote attacker could possibly use these flaws to perform an SQL injectionattack against an application using rubygem-actionpack andrubygem-activerecord. (CVE-2012-2660, CVE-2012-2694)A flaw was found in the HTTP digest authentication implementation inrubygem-actionpack. A remote attacker could use this flaw to cause adenial of service of an application using rubygem-actionpack and digestauthentication. (CVE-2012-3424)A flaw was found in the handling of strings in Ruby safe level 4. A remoteattacker can use Exception#tos to destructively modify an untainted stringso that it is tainted, the string can then be arbitrarily modified.(CVE-2012-4466)A flaw was found in the method for translating an exception message into astring in the Ruby Exception class. A remote attacker could use this flawto bypass safe level 4 restrictions, allowing untrusted (tainted) code tomodify arbitrary, trusted (untainted) strings, which safe level 4restrictions would otherwise prevent. (CVE-2012-4464)It was found that rubyparser from rubygem-rubyparser created a temporaryfile in an insecure way. A local attacker could use this flaw to perform asymbolic link attack, overwriting arbitrary files accessible to theapplication using rubyparser. (CVE-2013-0162)The CVE-2013-0162 issue was discovered by Michael Scherer of the Red HatRegional IT team.Users are advised to upgrade to Red Hat OpenShift Enterprise 1.1.1.
