Description

Red Hat Subscription Asset Manager acts as a proxy for handling
subscription information and software updates on client machines. Red Hat
Subscription Asset Manager is built on Ruby on Rails, a
model-view-controller (MVC) framework for web application development.
Action Pack implements the controller and the view components.

A directory traversal flaw was found in the way Ruby on Rails handled
wildcard segments in routes with implicit rendering. A remote attacker
could use this flaw to retrieve arbitrary local files accessible to a Ruby
on Rails application using the aforementioned routes via a specially
crafted request. (CVE-2014-0130)

A flaw was found in the way Ruby on Rails handled hashes in certain
queries. A remote attacker could use this flaw to perform a denial of
service (resource consumption) attack by sending specially crafted queries
that would result in the creation of Ruby symbols, which were never garbage
collected. (CVE-2013-1854)

Two cross-site scripting (XSS) flaws were found in Action Pack. A remote
attacker could use these flaws to conduct XSS attacks against users of an
application using Action Pack. (CVE-2013-1855, CVE-2013-1857)

It was discovered that the internationalization component of Ruby on Rails
could, under certain circumstances, return a fallback HTML string that
contained user input. A remote attacker could possibly use this flaw to
perform a reflective cross-site scripting (XSS) attack by providing a
specially crafted input to an application using the aforementioned
component. (CVE-2013-4491)

A denial of service flaw was found in the header handling component of
Action View. A remote attacker could send strings in specially crafted
headers that would be cached indefinitely, which would result in all
available system memory eventually being consumed. (CVE-2013-6414)

It was found that the number_to_currency Action View helper did not
properly escape the unit parameter. An attacker could use this flaw to
perform a cross-site scripting (XSS) attack on an application that uses
data submitted by a user in the unit parameter. (CVE-2013-6415)

Red Hat would like to thank Ruby on Rails upstream for reporting these
issues. Upstream acknowledges Ben Murphy as the original reporter of
CVE-2013-1854, Charlie Somerville as the original reporter of
CVE-2013-1855, Alan Jenkins as the original reporter of CVE-2013-1857,
Peter McLarnan as the original reporter of CVE-2013-4491, Toby Hsieh as the
original reporter of CVE-2013-6414, and Ankit Gupta as the original
reporter of CVE-2013-6415.

All Subscription Asset Manager users are advised to upgrade to these
updated packages, which contain backported patches to correct these issues.
