DESCRIPTION:
Multiple vulnerabilities have been reported in Opera, which can be
exploited by malicious people to conduct spoofing attacks, bypass
certain security restrictions, and potentially compromise a user's
system.

1) An error when displaying the download dialog box within a small
window can be exploited to download and execute a file by tricking a
user into entering a specific keyboard sequence.

2) An error when displaying the download dialog box can be exploited
to overlay the box with other content subsequently tricking a user
into downloading and executing a file.

3) An error when handling history.state of sites implementing
history.pushState and history.replaceState can be exploited to bypass
the cross-domain policy restriction and disclose certain information
to other sites.

4) An error when displaying certain dialogs can be exploited to
display arbitrary content while showing the URL of a trusted web site
in the address bar.

5) An error when handling redirects to a slowly responding, trusted
site can be exploited to display arbitrary content while showing the
URL of a trusted web site in the address bar.

The vulnerabilities are reported in versions prior to 11.62.

SOLUTION:
Update to version 11.62.

PROVIDED AND/OR DISCOVERED BY:
1,2,5) The vendor credits Jordi Chancel.
3,4) Reported by the vendor.
