Summary
`Zend_Feed_Rss` and `Zend_Feed_Atom` were found to contain potential XML eXternal Entity (XXE) vectors due to insecure usage of PHP's DOM extension. External entities could be specified by adding a specific DOCTYPE element to feeds; exploiting this vulnerability could coerce opening arbitrary files and/or TCP connections.
A similar issue was fixed for 1.11.13 and 1.12.0, in the `Zend_Feed::import()` factory method; however, the reporter of the issue discovered that the individual classes contained similar functionality in their constructors which remained vulnerable.
