Description Andreas Stieger 2015-04-01 10:33:13 UTC
Use-after-free due to type confusion flaws

Announced:     March 31, 2015
Reporter:     Nils
Impact:     Critical
Products:     Firefox
Fixed in:
        Firefox 37


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.
