SECUNIA ADVISORY ID:
SA36001
VERIFY ADVISORY:
http://secunia.com/advisories/36001/
DESCRIPTION:
Juan Pablo Lopez Yacubian has discovered a security issue in Mozilla
Firefox, which can be exploited by malicious people to display a fake
URL in the address bar.
The security issue is caused due to an error when opening a new
window for a malformed domain. This can be exploited to display an
arbitrary URL in the address bar of a child window by issuing a
"window.open()" call with a domain containing e.g. "%20" characters.
The security issue is confirmed in version 3.0.12 and 3.5.1. Other
versions may also be affected.
SOLUTION:
Do not browse untrusted websites or follow untrusted links.
PROVIDED AND/OR DISCOVERED BY:
