Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

An updated thunderbird package that fixes several security issues is
now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having
moderate security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.

Mozilla Thunderbird is a standalone mail and newsgroup client.

A race condition flaw was found in the way Thunderbird handled
Document Object Model (DOM) element properties. 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-2010-3765)

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-2010-3175,
CVE-2010-3176, CVE-2010-3179, CVE-2010-3180, CVE-2010-3183)

A same-origin policy bypass flaw was found in Thunderbird. Remote HTML
content could steal private data from different remote HTML content
Thunderbird had loaded. (CVE-2010-3178)

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.
