Thunderbird. (CVE-2013-5609, CVE-2013-5616, CVE-2013-5618,
A flaw was found in the way Thunderbird rendered web content with
missing character encoding information. An attacker could use this
flaw to possibly bypass same-origin inheritance and perform cross
site-scripting (XSS) attacks. (CVE-2013-5612)
It was found that certain malicious web content could bypass
restrictions applied by sandboxed iframes. An attacker could combine
this flaw with other vulnerabilities to execute arbitrary code with
the privileges of the user running Thunderbird. (CVE-2013-5614)
