    firefox vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 19.10
    - Ubuntu 19.04
    - Ubuntu 18.04 LTS
    - Ubuntu 16.04 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, bypass security
    restrictions, bypass same-origin restrictions, conduct cross-site
    scripting (XSS) attacks, bypass content security policy (CSP)
    protections, or execute arbitrary code.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 19.10:
      firefox                         70.0+build2-0ubuntu0.19.10.1
    
    Ubuntu 19.04:
      firefox                         70.0+build2-0ubuntu0.19.04.1
    
    Ubuntu 18.04 LTS:
      firefox                         70.0+build2-0ubuntu0.18.04.1
    
    Ubuntu 16.04 LTS:
      firefox                         70.0+build2-0ubuntu0.16.04.1
    
    After a standard system update you need to restart Firefox to make
    all the necessary changes.
