    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 19.10
    - Ubuntu 18.04 LTS
    
    Summary:
    
    Firefox could be made to crash or run programs as your login if it
    opened a malicious website.
    
    Software Description:
    - firefox: Mozilla Open Source web browser
    
    Details:
    
    Multiple security issues were discovered in Firefox. If a user were tricked
    in to opening a specially crafted website, an attacker could potentially
    exploit these to cause a denial of service, conduct cross-site scripting

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

      firefox                         73.0+build3-0ubuntu0.19.10.1

      firefox                         73.0+build3-0ubuntu0.18.04.1
    
    After a standard system update you need to restart Firefox to make
    all the necessary changes.
