Oracle Linux 4 : thunderbird (ELSA-2012-0085)

Synopsis :

The remote Oracle Linux host is missing a security update.

Description :

From Red Hat Security Advisory 2012:0085 :

An updated thunderbird package that fixes two security issues is now
available for Red Hat Enterprise Linux 4 and 5.

The Red Hat Security Response Team has rated this update as having
critical 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 flaw was found in the processing of malformed 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-2012-0442)

The same-origin policy in Thunderbird treated http://example.com and
http://[example.com] as interchangeable. A malicious script could
possibly use this flaw to gain access to sensitive information (such
as a client's IP and user e-mail address, or httpOnly cookies) that
may be included in HTTP proxy error replies, generated in response to
invalid URLs using square brackets. (CVE-2011-3670)

Note: The CVE-2011-3670 issue cannot be exploited by a
specially-crafted HTML mail message as JavaScript is disabled by
default for mail messages. It could be exploited another way in
Thunderbird, for example, when viewing the full remote content of an
RSS feed.

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.
