Description Huzaifa S. Sidhpurwala 2014-11-30 23:15:18 EST

Security researcher Berend-Jan Wever reported a use-after-free created by triggering the creation of a second root element while parsing HTML written to a document created with document.open(). This leads to a potentially exploitable crash.

In general this flaw cannot be exploited through email in the Thunderbird product because scripting is disabled, but is potentially a risk in browser or browser-like contexts.
