    firefox vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 18.04 LTS
    - Ubuntu 16.04 LTS
    - Ubuntu 14.04 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, or execute
    arbitrary code. (CVE-2018-12375, CVE-2018-12376, CVE-2018-12377,
    CVE-2018-12378)
    
    It was discovered that if a user saved passwords before Firefox 58 and
    then later set a master password, an unencrypted copy of these passwords
    would still be accessible. A local user could exploit this to obtain
    sensitive information. (CVE-2018-12383)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 18.04 LTS:
      firefox                         62.0+build2-0ubuntu0.18.04.3
    
    Ubuntu 16.04 LTS:
      firefox                         62.0+build2-0ubuntu0.16.04.3
    
    Ubuntu 14.04 LTS:
      firefox                         62.0+build2-0ubuntu0.14.04.3
    
    After a standard system update you need to restart Firefox to make
    all the necessary changes.
