3. Description:

 

The ruby193 collection provides Ruby version 1.9.3 and Ruby on Rails

version 3.2. Ruby on Rails is a model-view-controller (MVC) framework for

web application development.

 

The following issues were corrected in rubygem-actionpack:

 

Multiple directory traversal flaws were 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 these flaws to render unexpected files and, possibly, execute

arbitrary code. (CVE-2016-0752, CVE-2016-2097)

 

A code injection 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 flaw to execute arbitrary code. (CVE-2016-2098)

 

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 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)

 

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, Jyoti Singh and Tobias Kraze (makandra) as original

reporters of CVE-2016-2097, Tobias Kraze (makandra) and joernchen

(Phenoelit) as original reporters of CVE-2016-2098, Aaron Patterson (Red

Hat) as the original reporter of CVE-2016-0751, Daniel Waterworth as the

original reporter of CVE-2015-7576, and Justin Coyne as the original

reporter of CVE-2015-7577.

 

All ruby193 collection rubygem-actionpack 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 ruby193 collection must be restarted for this update to take effect.
