3. Description:

Mozilla Thunderbird is a standalone mail and newsgroup client.

Several flaws were found in the processing of malformed HTML mail content.
An HTML mail message containing malicious content could cause Thunderbird
to crash or, potentially, execute arbitrary code with the privileges of the
user running Thunderbird. (CVE-2010-3169)

A buffer overflow flaw was found in Thunderbird. An HTML mail message
containing malicious content could cause Thunderbird to crash or,
potentially, execute arbitrary code with the privileges of the user running
Thunderbird. (CVE-2010-2765)

A use-after-free flaw and several dangling pointer flaws were found in
Thunderbird. An HTML mail message containing malicious content could cause
Thunderbird to crash or, potentially, execute arbitrary code with the
privileges of the user running Thunderbird. (CVE-2010-2760, CVE-2010-2767,
CVE-2010-3167, CVE-2010-3168)

A cross-site scripting (XSS) flaw was found in Thunderbird. Remote HTML
content could cause Thunderbird to execute JavaScript code with the
permissions of different remote HTML content. (CVE-2010-2768)

Note: JavaScript support is disabled by default in Thunderbird. None of the
above issues are exploitable unless JavaScript is enabled.

All Thunderbird users should upgrade to this updated package, which
resolves these issues. All running instances of Thunderbird must be
restarted for the update to take effect.
