(CVE-2014-1477, CVE-2014-1482, CVE-2014-1486)
A flaw was found in the way Thunderbird handled error messages related to
web workers. An attacker could use this flaw to bypass the same-origin

potentially be used to gather authentication tokens and other data from
third-party websites. (CVE-2014-1487)
A flaw was found in the implementation of System Only Wrappers (SOW). An
attacker could use this flaw to crash Thunderbird. When combined with
other vulnerabilities, this flaw could have additional security
window objects. A remote attacker could use this flaw to bypass certain
security checks and possibly execute arbitrary code. (CVE-2014-1481)
