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)
