Input Validation Bypass

OpenShift Enterprise is a cloud computing Platform-as-a-Service (PaaS) solution from Red Hat, and is designed for on-premise or private cloud deployments. A flaw was found in the handling of paths provided to ruby193-rubygem-rack. A remote attacker could use this flaw to conduct a directory traversal attack by passing malformed requests. (CVE-2013-0262) A timing attack flaw was found in the way rubygem-rack and ruby193-rubygem-rack processed HMAC digests in cookies. This flaw could aid an attacker using forged digital signatures to bypass authentication checks. (CVE-2013-0263) It was found that Jenkins did not protect against Cross-Site Request Forgery (CSRF) attacks. If a remote attacker could trick a user, who was logged into Jenkins, into visiting a specially-crafted URL, the attacker could perform operations on Jenkins. (CVE-2013-0327, CVE-2013-0329) A cross-site scripting (XSS) flaw was found in Jenkins. A remote attacker could use this flaw to conduct an XSS attack against users of Jenkins. (CVE-2013-0328) A flaw could allow a Jenkins user to build jobs they do not have access to. (CVE-2013-0330) A flaw could allow a Jenkins user to cause a denial of service if they are able to supply a specially-crafted payload. (CVE-2013-0331) Users are advised to upgrade to Red Hat OpenShift Enterprise 1.1.2. It is recommended that you restart your system after applying this update.
