Synopsis: Moderate: thunderbird security update Issue date: 2010-12-09 CVE Names: CVE-2010-3768 CVE-2010-3776 CVE-2010-3777 Several flaws were found in the processing of malformed HTML content. Malicious HTML content could cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2010-3776, CVE-2010-3777) Note: JavaScript support is disabled in Thunderbird for mail messages. The above issues are believed to not be exploitable without JavaScript. This update adds support for the Sanitiser for OpenType (OTS) library to Thunderbird. This library helps prevent potential exploits in malformed OpenType fonts by verifying the font file prior to use. (CVE-2010-3768) All running instances of Thunderbird must be restarted for the update to take effect.
