The Ubuntu security team deemed this advisory irrelevant for Ubuntu:14.04.
NVD Description
Note: Versions mentioned in the description apply only to the upstream thunderbird package and not the thunderbird package as distributed by Ubuntu.
Mozilla Firefox before 41.0 does not properly restrict the availability of High Resolution Time API times, which allows remote attackers to track last-level cache access, and consequently obtain sensitive information, via crafted JavaScript code that makes performance.now calls.
