Description Huzaifa S. Sidhpurwala 2014-07-21 04:59:09 UTC 
Security researcher Jethro Beekman of the University of California, Berkeley reported a crash when the FireOnStateChange event is triggered in some circumstances. This leads to a use-after-free and a potentially exploitable crash when it occurs.

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.
