RedHat Update for thunderbird RHSA-2011:0312-01

Solution
Please Install the Updated Packages.
Insight
Mozilla Thunderbird is a standalone mail and newsgroup client. 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-2011-0051, CVE-2011-0053) 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.
Affected
thunderbird on Red Hat Enterprise Linux AS version 4, Red Hat Enterprise Linux ES version 4, Red Hat Enterprise Linux WS version 4
