3. Description:

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-2010-3176, CVE-2010-3180)

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

A flaw was found in the script that launches Thunderbird. The
LD_LIBRARY_PATH variable was appending a "." character, which could allow a
local attacker to execute arbitrary code with the privileges of a different
user running Thunderbird, if that user ran Thunderbird from within an
attacker-controlled directory. (CVE-2010-3182)

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.
