Description
Mozilla community member Alice White reported that when the
GetProperty function is invoked through JSAPI, security checking
can be bypassed when getting cross-origin properties. This potentially allowed
for arbitrary code execution.
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.
