Zend Framework 1.11.3 in Zend Server CE 5.1.0 allows remote attackers to obtain sensitive information via a direct request to a .php file, which reveals the installation path in an error message, as demonstrated by Validate.php and certain other files.
The (1) Zend_Feed_Rss and (2) Zend_Feed_Atom classes in Zend_Feed in Zend Framework 1.11.x before 1.11.15 and 1.12.x before 1.12.1 allow remote attackers to read arbitrary files, send HTTP requests to intranet servers, and possibly cause a denial of service (CPU and memory consumption) via an XML External Entity (XXE) attack.
