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.
