Updated thunderbird packages fix security vulnerabilities

Updated thunderbird packages fix security vulnerabilities: Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird (CVE-2015-7201, CVE-2015-7205, CVE-2015-7210, CVE-2015-7212, CVE-2015-7213, CVE-2015-7222). A flaw was found in the way Thunderbird handled content using the ‘data:’ and ‘view-source:’ URIs. An attacker could use this flaw to bypass the same-origin policy and read data from cross-site URLs and local files (CVE-2015-7214).
