The nsCSPHostSrc::permits function in dom/security/nsCSPUtils.cpp in
Mozilla Firefox before 40.0 does not implement the Content Security Policy
Level 2 exceptions for the blob, data, and filesystem URL schemes during
wildcard source-expression matching, which might make it easier for remote
attackers to conduct cross-site scripting (XSS) attacks by leveraging
unexpected policy-enforcement behavior.
