Mozilla Thunderbird is a standalone mail and newsgroup client.
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-2014-1518, CVE-2014-1524, CVE-2014-1529, CVE-2014-1531)
A use-after-free flaw was found in the way Thunderbird resolved hosts in certain circumstances. An attacker could use this flaw to crash Thunderbird or, potentially, execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2014-1532)

(CVE-2014-1530)
