CVE-2015-0804: Use After Free
First published: Wed Apr 01 2015(Updated: )
The HTMLSourceElement::BindToTree function in Mozilla Firefox before 37.0 does not properly constrain a data type after omitting namespace validation during certain tree-binding operations, which allows remote attackers to execute arbitrary code or cause a denial of service (use-after-free) via a crafted HTML document containing a SOURCE element.
