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) Reported by Stefano Di Paola.
2) Reported by the vendor.
