    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,

    Multiple security issues were discovered in the Graphite 2 library used
    by Thunderbird. If a user were tricked in to opening a specially crafted
    message, an attacker could potentially exploit these to cause a denial of
    service, read uninitialized memory, or execute arbitrary code.
    (CVE-2017-7771, CVE-2017-7772, CVE-2017-7773, CVE-2017-7774, CVE-2017-7775,
    CVE-2017-7776, CVE-2017-7777, CVE-2017-7778)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 17.04:
      thunderbird                     1:52.2.1+build1-0ubuntu0.17.04.1
    
    Ubuntu 16.10:
      thunderbird                     1:52.2.1+build1-0ubuntu0.16.10.1
    
    Ubuntu 16.04 LTS:
      thunderbird                     1:52.2.1+build1-0ubuntu0.16.04.1
    
    Ubuntu 14.04 LTS:
      thunderbird                     1:52.2.1+build1-0ubuntu0.14.04.1
