3. Description:
The rh-ror41 collection provides Ruby on Rails version 4.1. Ruby on Rails
is a model-view-controller (MVC) framework for web application development.
The following issue was corrected in rubygem-actionpack and
rubygem-actionview:
A directory traversal flaw was found in the way the Action View component
searched for templates for rendering. If an application passed untrusted
input to the 'render' method, a remote, unauthenticated attacker could use
this to render unexpected files and, possibly, execute arbitrary code.
(CVE-2016-0752)
The following issues were corrected in rubygem-actionpack:
A flaw was found in the way the Action Pack component performed MIME type
lookups. Since queries were cached in a global cache of MIME types, an
attacker could use this flaw to grow the cache indefinitely, potentially
resulting in a denial of service. (CVE-2016-0751)
A flaw was found in the Action Pack component's caching of controller
references. An attacker could use this flaw to cause unbounded memory
growth, potentially resulting in a denial of service. (CVE-2015-7581)
A flaw was found in the way the Action Controller component compared user
names and passwords when performing HTTP basic authentication. Time taken
to compare strings could differ depending on input, possibly allowing a
remote attacker to determine valid user names and passwords using a timing
attack. (CVE-2015-7576)
The following issue was corrected in rubygem-activerecord:
A flaw was found in the Active Record component's handling of nested
attributes in combination with the destroy flag. An attacker could possibly
use this flaw to set attributes to invalid values or clear all attributes.
(CVE-2015-7577)
The following issue was corrected in rubygem-activemodel and
rubygem-activerecord:
A flaw was found in the way the Active Model based models processed
attributes. An attacker with the ability to pass arbitrary attributes to
models could possibly use this flaw to bypass input validation.
(CVE-2016-0753)
Red Hat would like to thank the Ruby on Rails project for reporting these
issues. Upstream acknowledges John Poulin as the original reporter of
CVE-2016-0752, Aaron Patterson of Red Hat as the original reporter of
CVE-2016-0751, Daniel Waterworth as the original reporter of CVE-2015-7576,
Justin Coyne as the original reporter of CVE-2015-7577, and John Backus
from BlockScore as the original reporter of CVE-2016-0753.
All rh-ror41 collection rubygem-actionpack, rubygem-actionview,
rubygem-activemodel, and rubygem-activerecord packages users are advised to
upgrade to these updated packages, which contain backported patches to
correct these issues. All running applications using the rh-ror41
collection must be restarted for this update to take effect.
