Google security researcher Chris Evans reported that a
website could access a limited amount of data from a different domain by
target resource containing data
context via the
window.onerror DOM API.
Update December 18, 2008: The Windows version of Firefox 220.127.116.11 was shipped without the fix for this issue (other platforms were correctly patched). Firefox 18.104.22.168 has been released on Windows to correct this oversight.
