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 22.214.171.124 was shipped without the fix for this issue (other platforms were correctly patched). Firefox 126.96.36.199 has been released on Windows to correct this oversight.
