Description Huzaifa S. Sidhpurwala 2012-11-17 11:36:08 UTC 
Mozilla developer Peter Van der Beken discovered that same-origin XrayWrappers expose chrome-only properties even when not in a chrome compartment. This can allow web content to get properties of DOM objects that are intended to be chrome-only.

In general these flaws cannot be exploited through email in the Thunderbird and SeaMonkey products because scripting is disabled, but are potentially a risk in browser or browser-like contexts in those products.
