Red Hat: 2011:1439-01: thunderbird: Critical Advisory
Summary
Mozilla Thunderbird is a standalone mail and newsgroup client.
A flaw was found in the way Thunderbird handled certain add-ons. Malicious,
remote content could cause an add-on to elevate its privileges, which could
lead to arbitrary code execution with the privileges of the user running
Thunderbird. (CVE-2011-3647)
A cross-site scripting (XSS) flaw was found in the way Thunderbird handled
certain multibyte character sets. Malicious, remote content could cause
Thunderbird to run JavaScript code with the permissions of different
remote content. (CVE-2011-3648)
A flaw was found in the way Thunderbird handled large JavaScript scripts.
Malicious, remote content could cause Thunderbird to crash or, potentially,
execute arbitrary code with the privileges of the user running Thunderbird.
(CVE-2011-3650)
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.
