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

1) Certain parameters passed to the "History Search" functionality 
are not properly sanitised before being used. This can be exploited
to inject arbitrary HTML and script code, which is executed in a
user's browser session when the malicious data is being viewed.

Successful exploitation allows e.g. changing Opera's preferences,
which can further be exploited to execute arbitrary commands.

This is related to vulnerability #1 in:
SA32299

2) An error exists in the handling of javascript URLs in the Links
panel, which can be exploited to conduct cross-site scripting attacks
with pages containing frames.

The vulnerabilities are reported in versions prior to 9.62.

SOLUTION:
Update to version 9.62 (see the vendor's advisory for details).

PROVIDED AND/OR DISCOVERED BY:
1) The vendor credits Aviv Raff.
2) Reported by the vendor.
