3. Description:

Mozilla Firefox is an open source web browser. XULRunner provides the XUL
Runtime environment for Mozilla Firefox.

A flaw was found in the way Firefox handled malformed JPEG images. A
website containing a malicious JPEG image could cause Firefox to crash or,
potentially, execute arbitrary code with the privileges of the user running
Firefox. (CVE-2011-2377)

Multiple dangling pointer flaws were found in Firefox. A web page
containing malicious content could cause Firefox to crash or, potentially,
execute arbitrary code with the privileges of the user running Firefox.
(CVE-2011-0083, CVE-2011-0085, CVE-2011-2363)

Several flaws were found in the processing of malformed web content. A web
page containing malicious content could cause Firefox to crash or,
potentially, execute arbitrary code with the privileges of the user running
Firefox. (CVE-2011-2364, CVE-2011-2365, CVE-2011-2374, CVE-2011-2375,
CVE-2011-2376)

An integer overflow flaw was found in the way Firefox handled JavaScript
Array objects. A website containing malicious JavaScript could cause
Firefox to execute that JavaScript with the privileges of the user running
Firefox. (CVE-2011-2371)

A use-after-free flaw was found in the way Firefox handled malformed
JavaScript. A website containing malicious JavaScript could cause Firefox
to execute that JavaScript with the privileges of the user running Firefox.
(CVE-2011-2373)

It was found that Firefox could treat two separate cookies as
interchangeable if both were for the same domain name but one of those
domain names had a trailing "." character. This violates the same-origin
policy and could possibly lead to data being leaked to the wrong domain.
(CVE-2011-2362)

For technical details regarding these flaws, refer to the Mozilla security
advisories for Firefox 3.6.18. You can find a link to the Mozilla
advisories in the References section of this erratum.

This update also fixes the following bug:

* With previous versions of Firefox on Red Hat Enterprise Linux 5, the
"background-repeat" CSS (Cascading Style Sheets) property did not work
(such images were not displayed and repeated as expected). (BZ#698313)

All Firefox users should upgrade to these updated packages, which contain
Firefox version 3.6.18, which corrects these issues. After installing the
update, Firefox must be restarted for the changes to take effect.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/kb/docs/DOC-11259

5. Bugs fixed (http://bugzilla.redhat.com/):

698313 - "background-repeat" css property isn't rendered well in Firefox 3.6.x

1. Summary:

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 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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64
Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64
Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64

3. Description:

Mozilla Thunderbird is a standalone mail and newsgroup client.

A flaw was found in the way Thunderbird handled malformed JPEG images. An
HTML mail message containing a malicious JPEG image could cause Thunderbird
to crash or, potentially, execute arbitrary code with the privileges of the
user running Thunderbird. (CVE-2011-2377)

Multiple dangling pointer flaws were found in Thunderbird. Malicious HTML
content could cause Thunderbird to crash or, potentially, execute arbitrary
code with the privileges of the user running Thunderbird. (CVE-2011-0083,
CVE-2011-0085, CVE-2011-2363)

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-2011-2364, CVE-2011-2365, CVE-2011-2374, CVE-2011-2375, CVE-2011-2376)

It was found that Thunderbird could treat two separate cookies (for web
content) as interchangeable if both were for the same domain name but one
of those domain names had a trailing "." character. This violates the
same-origin policy and could possibly lead to data being leaked to the
wrong domain. (CVE-2011-2362)

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.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/kb/docs/DOC-11259
