DESCRIPTION:
Multiple vulnerabilities have been reported in Opera, which can be
exploited by malicious people to conduct cross-site scripting attacks
and compromise a user's system.

1) An error when handling certain DOM elements can be exploited to
bypass the HTML sanitizer and conduct cross-site scripting attacks.

2) An error when handling certain HTML characters can be exploited to
bypass the HTML sanitizer and conduct cross-site scripting attacks.

3) 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.

The vulnerabilities are reported in versions prior to 12.01 and 11.66
