    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 19.10

    Summary:
    
    Several security issues were fixed in Thunderbird.
    
    Software Description:
    - thunderbird: Mozilla Open Source mail and newsgroup client
    
    Details:
    
    Multiple security issues were discovered in Thunderbird. If a user were
    tricked in to opening a specially crafted website in a browsing context,
    an attacker could potentially exploit these to cause a denial of service,
    conduct cross-site scripting (XSS) attacks, or execute arbitrary code.
    (CVE-2019-17005, CVE-2019-17008, CVE-2019-17010, CVE-2019-17011,
    CVE-2019-17012, CVE-2019-17016, CVE-2019-17017, CVE-2019-17022,
    CVE-2019-17024, CVE-2019-17026)
    
    It was discovered that NSS incorrectly handled certain memory operations.
    A remote attacker could potentially exploit this to cause a denial of
    service, or execute arbitrary code. (CVE-2019-11745)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 19.10:
      thunderbird                     1:68.4.1+build1-0ubuntu0.19.10.1
    
    Ubuntu 18.04 LTS:
      thunderbird                     1:68.4.1+build1-0ubuntu0.18.04.1
    
    After a standard system update you need to restart Thunderbird to make
    all the necessary changes.
