How to fix?

There is no fixed version for Ubuntu:14.04 jquery.

NVD Description

Note: Versions mentioned in the description apply only to the upstream jquery package and not the jquery package as distributed by Ubuntu. See How to fix? for Ubuntu:14.04 relevant fixed versions and status.

jQuery before 1.9.0 is vulnerable to Cross-site Scripting (XSS) attacks. The jQuery(strInput) function does not differentiate selectors from HTML in a reliable fashion. In vulnerable versions, jQuery determined whether the input was HTML by looking for the '<' character anywhere in the string, giving attackers more flexibility when attempting to construct a malicious payload. In fixed versions, jQuery only deems the input to be HTML if it explicitly starts with the '<' character, limiting exploitability only to attackers who can control the beginning of a string, which is far less common.
