(RHSA-2014:0215) Critical: cfme security, bug fix, and enhancement update

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.
