13 February 2013

jquery vulnerability

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

  • Ubuntu 11.10
  • Ubuntu 10.04 LTS


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

Software Description

  • jquery - JavaScript library for dynamic web applications


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.
