Mozilla Foundation Security Advisory 2008-65
Title: Cross-domain data theft via script redirect error message
Announced: December 16, 2008
Reporter: Chris Evans
Products: Firefox, Thunderbird, SeaMonkey
Fixed in: Firefox 3.0.5
Firefox 220.127.116.11, 18.104.22.168
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.
