thunderbird security update

CentOS Errata and Security Advisory CESA-2010:0968

Mozilla Thunderbird is a standalone mail and newsgroup client.

Several flaws were found in the processing of malformed HTML content. HTML
containing malicious content could cause Thunderbird to crash or,
potentially, execute arbitrary code with the privileges of the user running
Thunderbird. (CVE-2010-3767, CVE-2010-3772, CVE-2010-3776)

Note: JavaScript support is disabled by default in Thunderbird. The above
issues are not 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.
