Welcome to the Zend Framework 1.12 Release!
Zend Framework 1.12.0 Release (r25051). Released on August 27, 2012.
SECURITY FIXES FOR 1.12.0
This release incorporates fixes for each of:
Several components were found to be vulnerable to XML eXternal Entity (XXE) Injection attacks due to insecure usage of the SimpleXMLElement class (SimpleXML PHP extension). External entities could be specified by adding a specific DOCTYPE element to XML-RPC requests; exploiting this vulnerability could coerce opening arbitrary files and/or TCP connections.
Additionally, these same components were found to be vulnerable to XML Entity Expansion (XEE) vectors. XEE attacks define custom entities within the DOCTYPE that refer to themselves, leading to recursion; the end result is excessive consumption of CPU and RAM, making Denial of Service (DoS) attacks easier to implement.
Vulnerable components included:
The patches applied do the following:
To remove XXE vectors, libxml_disable_entity_loader() is called before any SimpleXML calls are executed.
To remove XEE vectors, we loop through the DOMDocument child nodes, ensuring none are of type XML_DOCUMENT_TYPE_NODE, and raising an exception if any are. If SimpleXML is used, a DOMDocument is created first, processed as above, and then passed to simplexml_import_dom.
The above patches are also available in the 1.11 series of releases.
Thanks goes to Johannes Greil and Kestutis Gudinavicius of SEC-Consult for reporting the original XXE vulnerability against Zend_XmlRpc and working with us to provide a working solution. Thanks goes to Pádraic Brady for helping us identify other XXE vectors, as well as identifying and patching the XEE vectors.
A number of autoloaders and autoloader facilities were back ported from ZF2 to provide performant alternatives to those already available in the 1.X releases. These include: Zend_Loader_StandardAutoloader, which improves on Zend_Loader_Autoloader by allowing the ability to specify a specific path to associate with a vendor prefix or namespace; Zend_Loader_ClassMapAutoloader, which provides the ability to use lookup tables for autoloading (which are typically the fastest possible way to autoload); and Zend_Loader_AutoloaderFactory, which can both create and update autoloaders for you, as well as register them with spl_autoload_register().
The Zend_Loader changes were back ported from ZF2 by Matthew Weier O’Phinney
Zend_EventManager is a component that allows you to attach and detach listeners to named events, both on a per-instance basis as well as via shared collections; trigger events; and interrupt execution of listeners.

This class provides a features adapter that calls get_browser() in order to discover mobile device capabilities to inject into UserAgent device instances.
Browscap (http://browsers.garykeith.com/) is an open project dedicated to collecting an disseminating a “database” of browser capabilities. PHP has built-in support for using these files via the get_browser() function. This function requires that your php.ini provides a browscap entry pointing to the PHP-specific php_browscap.ini file which is available at http://browsers.garykeith.com/stream.asp?PHP_BrowsCapINI.
Zend_Http_UserAgent_Features_Adapter_Browscap was created by Matthew Weier O’Phinney
Zend_Mobile_Push is a component for implementing push notifications for the 3 major push notification platforms (Apple (Apns), Google (C2dm) and Microsoft (Mpns).
Zend_Mobile_Push was contributed by Mike Willbanks.
Zend_Gdata_Analytics is an extension to Zend_Gdata to allow interaction with Google’s Analytics Data Export API. This extension does not encompass any major changes in the overall operation of Zend_Gdata components.
Zend_Gdata_Analytics was contributed by Daniel Hartmann.
Due to the changes in licensing of WURFL, we have removed the WurflApi adapter. We will be providing the WurflApi adapter to ScientiaMobile so that users of WURFL will still have that option.
In addition, over 200 reported issues in the tracker have been fixed. We’d like to particularly thank Adam Lundrigan, Frank Brückner and Martin Hujer for their efforts in making this happen. Thanks also to the many people who ran the ZF1 unit tests and reported their results!
