(Red Hat Issues Fix for Mozilla Seamonkey) Mozilla Firefox Invalid Character URL Bug Lets Remote Users Spoof URLs
SecurityTracker Alert ID:  1022893
SecurityTracker URL:  http://securitytracker.com/id/1022893
CVE Reference:   CVE-2009-2654   (Links to External Site)
Date:  Sep 10 2009
Impact:   Modification of system information
Fix Available:  Yes  Vendor Confirmed:  Yes  

Description:   A vulnerability was reported in Mozilla Firefox. A remote user can spoof URLs. Mozilla Seamonkey is affected.

A remote user can create specially crafted HTML that, when loaded by the target user, will load an arbitrary URL containing an invalid character. The address bar will display a portion of the URL (spoofing a valid URL) and the browser will display arbitrary page contents instead of the invalid URL error page.

A demonstration exploit is available at:

http://es.geocities.com/jplopezy/firefoxspoofing.html

Juan Pablo Lopez Yacubian reported this vulnerability.

Impact:   A remote user can spoof URLs.
Solution:   Red Hat has released a fix for Mozilla Seamonkey.

=====================================================================

1. Summary:

Updated seamonkey packages that fix several security issues are now
available for Red Hat Enterprise Linux 3.

This update has been rated as having critical security impact by the Red
Hat Security Response Team.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Desktop version 3 - i386, x86_64
Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64

3. Description:

SeaMonkey is an open source Web browser, email and newsgroup client, IRC
chat client, and HTML editor.

Several flaws were found in the processing of malformed web content. A web
page containing malicious content could cause SeaMonkey to crash or,
potentially, execute arbitrary code with the privileges of the user running
SeaMonkey. (CVE-2009-3072, CVE-2009-3075)

A use-after-free flaw was found in SeaMonkey. An attacker could use this
flaw to crash SeaMonkey or, potentially, execute arbitrary code with the
privileges of the user running SeaMonkey. (CVE-2009-3077)

Dan Kaminsky discovered flaws in the way browsers such as SeaMonkey handle
NULL characters in a certificate. If an attacker is able to get a
carefully-crafted certificate signed by a Certificate Authority trusted by
SeaMonkey, the attacker could use the certificate during a
man-in-the-middle attack and potentially confuse SeaMonkey into accepting
it by mistake. (CVE-2009-2408)

Descriptions in the dialogs when adding and removing PKCS #11 modules were
not informative. An attacker able to trick a user into installing a
malicious PKCS #11 module could use this flaw to install their own
Certificate Authority certificates on a user's machine, making it possible
to trick the user into believing they are viewing a trusted site or,
potentially, execute arbitrary code with the privileges of the user running
SeaMonkey. (CVE-2009-3076)

A flaw was found in the way SeaMonkey displays the address bar when
window.open() is called in a certain way. An attacker could use this flaw
to conceal a malicious URL, possibly tricking a user into believing they
are viewing a trusted site. (CVE-2009-2654)

Dan Kaminsky found that browsers still accept certificates with MD2 hash
signatures, even though MD2 is no longer considered a cryptographically
strong algorithm. This could make it easier for an attacker to create a
malicious certificate that would be treated as trusted by a browser. NSS
(provided by SeaMonkey) now disables the use of MD2 and MD4 algorithms
inside signatures by default. (CVE-2009-2409)

All SeaMonkey users should upgrade to these updated packages, which correct
these issues. After installing the update, SeaMonkey must be restarted for
the changes to take effect.

4. Solution:

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

This update is available via 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

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

510197 - CVE-2009-2409 deprecate MD2 in SSL cert validation (Kaminsky)
