The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2250-1 advisory.

    Gary Kwong, Christoph Diehl, Christian Holler, Hannes Verschore, Jan de Mooij, Ryan VanderMeulen, Jeff     Walden and Kyle Huey discovered multiple memory safety issues in Thunderbird. If a user were tricked in to     opening a specially crafted message with scripting enabled, an attacker could potentially exploit these to     cause a denial of service via application crash, or execute arbitrary code with the privileges of the user     invoking Thunderbird. (CVE-2014-1533)

    Abhishek Arya discovered multiple use-after-free and out-of-bounds read issues in Thunderbird. If a user     had enabled scripting, an attacker could potentially exploit these to cause a denial of service via     application crash or execute arbitrary code with the priviliges of the user invoking Thunderbird.
    (CVE-2014-1538)

    A use-after-free was discovered in the SMIL animation controller. If a user had enabled scripting, an     attacker could potentially exploit this to cause a denial of service via application crash or execute     arbitrary code with the priviliges of the user invoking Thunderbird. (CVE-2014-1541)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.
