Description Huzaifa S. Sidhpurwala 2015-03-30 08:13:44 UTC 
Security researcher Nils used the Address Sanitizer tool to discover two type confusion flaws. The first of these occurs while setting specific attributes of a source element resulting in incorrect object casting. The second flaw occurs when binding a source to a tree when the function fails to validate the namespace. These flaws lead to use-after-free errors, resulting in potentially exploitable crashes.
