Arbitrary Code Execution

Red Hat CloudForms Management Engine delivers the insight, control, and automation enterprises need to address the challenges of managing virtual environments, which are far more complex than physical ones. This technology enables enterprises with existing virtual infrastructures to improve visibility and control, and those just starting virtualization deployments to build and operate a well-managed virtual infrastructure. A buffer overflow flaw was found in the way Ruby parsed floating point numbers from their text representation. If an application using Ruby accepted untrusted input strings and converted them to floating point numbers, an attacker able to provide such input could cause the application to crash or, possibly, execute arbitrary code with the privileges of the application. (CVE-2013-4164) It was found that Red Hat CloudForms Management Engine did not properly sanitize user-supplied values in the ServiceController. A remote attacker could invoke arbitrary method calls in the application controller that, due to a lack of sanitization, could allow access to private methods that could possibly allow the attacker to execute arbitrary code on the host system. (CVE-2014-0057) It was found that several number conversion helpers in Action View did not properly escape all their parameters. An attacker could use these flaws to perform a cross-site scripting (XSS) attack on an application that uses data submitted by a user as parameters to the affected helpers. (CVE-2014-0081) A memory consumption issue was discovered in the text rendering component of Action View. A remote attacker could use this flaw to perform a denial of service attack by sending specially crafted queries that would result in the creation of Ruby symbols that were never garbage collected. (CVE-2014-0082) Red Hat would like to thank the Ruby on Rails Project for reporting CVE-2014-0081 and CVE-2014-0082. Upstream acknowledges Kevin Reintjes as the original reporter of CVE-2014-0081, and Toby Hsieh of SlideShare as the original reporter of CVE-2014-0082. The CVE-2014-0057 issue was discovered by Jan Rusnacko of the Red Hat Product Security Team. This update fixes several bugs and adds multiple enhancements. Documentation for these changes will be available shortly from the Red Hat CloudForms 3.0 Management Engine 5.2 Technical Notes linked to in the References section. All users of Red Hat CloudForms are advised to upgrade to these updated packages, which contain backported patches to correct these issues and add these enhancements.
