jquery vulnerability
============================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 11.10
- Ubuntu 10.04 LTS

Summary:

jQuery could be made to expose sensitive information over the network.

Software Description:
- jquery: JavaScript library for dynamic web applications

Details:

It was discovered that jQuery incorrectly handled selecting elements using
location.hash, resulting in a possible cross-site scripting (XSS) issue.
With cross-site scripting vulnerabilities, if a user were tricked into
viewing a specially crafted page, a remote attacker could exploit this to
modify the contents, or steal confidential data, within the same domain.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 11.10:
  libjs-jquery                    1.6.2-1ubuntu2.2

Ubuntu 10.04 LTS:
  libjs-jquery                    1.3.3-2ubuntu1.2

In general, a standard system update will make all the necessary changes.
