DESCRIPTION:
Multiple vulnerabilities have been reported in YUI, which can be
exploited by malicious users to conduct script insertion attacks.

For more information see vulnerabilities #3 and #5:
SA43033

1) Certain Input passed to the "addItem()" method is not properly
sanitised before being used in the Menu widget. This can be exploited
to insert arbitrary HTML and script code, which will be executed in a
user's browser session in context of an affected site when the
malicious data is being viewed.

The vulnerabilities are reported in versions prior to 2.9.0.

SOLUTION:
Fixed in the GIT repository. Update to version 2.9.0 when it becomes
available.

PROVIDED AND/OR DISCOVERED BY:
1) Reported by jkl in a YUI forum post.
