Description Vincent Danen 2014-04-29 16:57:02 UTC 
Security researcher Abhishek Arya (Inferno) of the Google Chrome Security Team used the Address Sanitizer tool to discover a buffer overflow when a script uses a non-XBL object as an XBL object because the XBL status of the object is not properly validated. The resulting memory corruption is potentially exploitable.

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