    firefox vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 19.04
    - Ubuntu 18.10
    - 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:
    
    A sandbox escape was discovered in Firefox. If a user were tricked in to
    installing a malicious language pack, an attacker could exploit this to
    gain additional privileges. (CVE-2019-9811)
    
    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, obtain sensitive
    information, bypass same origin restrictions, conduct cross-site scripting
    (XSS) attacks, conduct cross-site request forgery (CSRF) attacks, spoof
    origin attributes, spoof the addressbar contents, bypass safebrowsing
    protections, or execute arbitrary code. (CVE-2019-11709, CVE-2019-11710,
    CVE-2019-11711, CVE-2019-11712, CVE-2019-11713, CVE-2019-11714,
    CVE-2019-11715, CVE-2019-11716, CVE-2019-11717, CVE-2019-11718,
    CVE-2019-11719, CVE-2019-11720, CVE-2019-11721, CVE-2019-11723,
    CVE-2019-11724, CVE-2019-11725, CVE-2019-11727, CVE-2019-11728,
    CVE-2019-11729)
    
    It was discovered that Firefox treats all files in a directory as same
    origin. If a user were tricked in to downloading a specially crafted HTML
    file, an attacker could potentially exploit this to obtain sensitive
    information from local files. (CVE-2019-11730)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 19.04:
      firefox                         68.0+build3-0ubuntu0.19.04.1
