Mandriva Linux Security Advisory 2013-115 - Zend_Dom, Zend_Feed, Zend_Soap, and Zend_XmlRpc in Zend Framework before 1.11.13 and 1.12.0 are vulnerable to XML Entity Expansion vectors, leading to Denial of Service vectors. XEE attacks occur when the XML DOCTYPE declaration includes XML entity definitions that contain either recursive or circular references; this leads to CPU and memory consumption, making Denial of Service exploits trivial to implement. A vulnerability was reported in Zend Framework versions prior to 1.11.15 and 1.12.1, which can be exploited to disclose certain sensitive information. This flaw is caused due to an error in the Zend_Feed_Rss and Zend_Feed_Atom classes of the Zend_Feed component, when processing XML data. It can be used to disclose the contents of certain local files by sending specially crafted XML data including external entity references.
