The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3416-1 advisory.

    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 bypass same-origin     restrictions, bypass CSP restrictions, obtain sensitive information, spoof the origin of modal alerts,     cause a denial of service via application crash, or execute arbitrary code. (CVE-2017-7753, CVE-2017-7779,     CVE-2017-7784, CVE-2017-7785, CVE-2017-7787, CVE-2017-7791, CVE-2017-7792, CVE-2017-7800, CVE-2017-7801,     CVE-2017-7802, CVE-2017-7803, CVE-2017-7807, CVE-2017-7809)

    A buffer overflow was discovered when displaying SVG content in some circumstances.
