Mozilla Thunderbird is a standalone mail and newsgroup client.
Several flaws were found in the processing of malformed content.
Malicious content could cause Thunderbird to crash or, potentially,
execute arbitrary code with the privileges of the user running
Thunderbird. (CVE-2012-3982, CVE-2012-3988, CVE-2012-3990,
CVE-2012-3995, CVE-2012-4179, CVE-2012-4180, CVE-2012-4181,
CVE-2012-4182, CVE-2012-4183, CVE-2012-4185, CVE-2012-4186,

Thunderbird executing arbitrary code. Note that the information
disclosure issue could possibly be combined with other flaws to
achieve arbitrary code execution. (CVE-2012-3986, CVE-2012-3991)
Multiple flaws were found in the location object implementation in
Thunderbird. Malicious content could be used to perform cross-site
scripting attacks, script injection, or spoofing attacks.
(CVE-2012-1956, CVE-2012-3992, CVE-2012-3994)
Two flaws were found in the way Chrome Object Wrappers were
implemented. Malicious content could be used to perform cross-site
scripting attacks or cause Thunderbird to execute arbitrary code.
