    - Ubuntu 19.04
    - Ubuntu 18.04 LTS
    - Ubuntu 16.04 LTS
    
    Summary:
    
    Firefox could be made to hijack the mouse pointer it if opened a malicious
    website.
    
    Software Description:

    Details:
    
    It was discovered that no user notification was given when pointer lock is
