3. Description:
Mozilla Firefox is an open source Web browser.
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 as the user running Firefox.
(CVE-2008-5500, CVE-2008-5501, CVE-2008-5502, CVE-2008-5511, CVE-2008-5512,
CVE-2008-5513)
Several flaws were found in the way malformed content was processed. A
website containing specially-crafted content could potentially trick a
Firefox user into surrendering sensitive information. (CVE-2008-5506,
CVE-2008-5507)
A flaw was found in the way Firefox stored attributes in XML User Interface
Language (XUL) elements. A web site could use this flaw to track users
across browser sessions, even if users did not allow the site to store
cookies in the victim's browser. (CVE-2008-5505)
A flaw was found in the way malformed URLs were processed by Firefox.
This flaw could prevent various URL sanitization mechanisms from properly
parsing a malicious URL. (CVE-2008-5508)
A flaw was found in Firefox's CSS parser. A malicious web page could inject
NULL characters into a CSS input string, possibly bypassing an
application's script sanitization routines. (CVE-2008-5510)
For technical details regarding these flaws, please see the Mozilla
security advisories for Firefox 3.0.5. You can find a link to the Mozilla
advisories in the References section.
Note: after the errata packages are installed, Firefox must be restarted
for the update to take effect.
All firefox users should upgrade to these updated packages, which contain
backported patches that correct these issues.

3. Description:
Mozilla Firefox is an open source Web browser. XULRunner provides the XUL
Runtime environment for Mozilla Firefox.
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-2009-3979, CVE-2009-3981, CVE-2009-3986)
A flaw was found in the Firefox NT Lan Manager (NTLM) authentication
protocol implementation. If an attacker could trick a local user that has
NTLM credentials into visiting a specially-crafted web page, they could
send arbitrary requests, authenticated with the user's NTLM credentials, to
other applications on the user's system. (CVE-2009-3983)
A flaw was found in the way Firefox displayed the SSL location bar
indicator. An attacker could create an unencrypted web page that appears to
be encrypted, possibly tricking the user into believing they are visiting a
secure page. (CVE-2009-3984)
A flaw was found in the way Firefox displayed blank pages after a user
navigates to an invalid address. If a user visits an attacker-controlled
web page that results in a blank page, the attacker could inject content
into that blank page, possibly tricking the user into believing they are
viewing a legitimate page. (CVE-2009-3985)
For technical details regarding these flaws, refer to the Mozilla security
advisories for Firefox 3.0.16. You can find a link to the Mozilla
advisories in the References section of this errata.
All Firefox users should upgrade to these updated packages, which contain
Firefox version 3.0.16, which corrects these issues. After installing the
update, Firefox must be restarted for the changes to take effect.

3. Description:
Mozilla Firefox is an open source web browser. XULRunner provides the XUL
Runtime environment for Mozilla Firefox.
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-2010-3169, CVE-2010-2762)
Several use-after-free and 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-2010-2760, CVE-2010-2766, CVE-2010-2767, CVE-2010-3167,
CVE-2010-3168)
Multiple buffer overflow 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-2010-2765, CVE-2010-3166)
Multiple cross-site scripting (XSS) flaws were found in Firefox. A web page
containing malicious content could cause Firefox to run JavaScript code
with the permissions of a different website. (CVE-2010-2768, CVE-2010-2769)
A flaw was found in the Firefox XMLHttpRequest object. A remote site could
use this flaw to gather information about servers on an internal private
network. (CVE-2010-2764)
For technical details regarding these flaws, refer to the Mozilla security
advisories for Firefox 3.6.9. You can find a link to the Mozilla advisories
in the References section of this erratum.
Note: After installing this update, Firefox will fail to connect (with
HTTPS) to a server using the SSL DHE (Diffie-Hellman Ephemeral) key
exchange if the server's ephemeral key is too small. Connecting to such
servers is a security risk as an ephemeral key that is too small makes the
SSL connection vulnerable to attack. Refer to the Solution section for
further information.
All Firefox users should upgrade to these updated packages, which contain
Firefox version 3.6.9, 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
http://kbase.redhat.com/faq/docs/DOC-11259
If you encounter the condition where Firefox fails to connect to a
server that has an ephemeral key that is too small, you can try
connecting using a cipher suite with a different key exchange algorithm
by disabling all DHE cipher suites in Firefox:
1) Type about:config in the URL bar and press the Enter key.
2) In the Filter search bar, type ssl3.dhe
3) For all preferences now presented, double-click the true value to
change the value to false.
Note: This change would affect connections to all HTTPS servers.
