Description

Multiple Mozilla products contain a weakness that may more easily allow a remote cross-site scripting (XSS) attack. This flaw exists because the application does not validate the content security policy header before returning it to the user. This may allow a user to create a specially crafted URL that would execute arbitrary script code in a user's browser within the trust relationship between their browser and the server.
