(Red Hat Issues Fix) Firefox onload() History Access Bug and Install Function Scripting Execution Flaw Lets Remote Users Execute Arbitrary Code
SecurityTracker Alert ID:  1014032
SecurityTracker URL:  http://securitytracker.com/id/1014032
CVE Reference:   CVE-2005-1476, CVE-2005-1477   (Links to External Site)
Date:  May 23 2005
Impact:   Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 1.0.3
Description:   Several vulnerabilities were reported in Firefox. A remote user can execute arbitrary code on the target user's system.

A remote user can create specially crafted HTML that, when loaded by the target user, will execute arbitrary code on the target user's system.

A remote user can cause a Firefox chrome page to load a 'javascript:' URL with privileges. The addon install function can be made to display an icon containing a 'javascript:' URL to achieve this.

Because the vulnerable install function can only be loaded via 'update.mozilla.org' or 'addon.mozilla.org', the remote user must exploit a separate vulnerability to trigger the flaw. The onload() event can be exploited via a frame within a javascript page to access ostensibly restricted elements of the window object, such as the history. The history object can be accessed to navigate back to the calling javascript page and execute the page within the context of a window (displaying 'mozilla.org' web page content).

A demonstration exploit is available at:

http://greyhatsecurity.org/vulntests/ffrc.htm

Paul from Greyhats Security reported this vulnerability. Michael Krax assisted in researching this vulnerability.

Impact:   A remote user can execute arbitrary code on the target user's system.
Solution:   Red Hat has released a fix.

- ---------------------------------------------------------------------

1. Summary:

Updated firefox packages that fix various security bugs are now available.

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

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, x86_64

3. Problem description:

Mozilla Firefox is an open source Web browser.

Several bugs were found in the way Firefox executes javascript code.
Javascript executed from a web page should run with a restricted access
level, preventing dangerous actions. It is possible that a malicious web
page could execute javascript code with elevated privileges, allowing
access to protected data and functions. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the names CAN-2005-1476,
CAN-2005-1477, CAN-2005-1531, and CAN-2005-1532 to these issues.

Please note that the effects of CAN-2005-1477 are mitigated by the default
setup, which allows only the Mozilla Update site to attempt installation of
Firefox extensions. The Mozilla Update site has been modified to prevent
this attack from working. If other URLs have been manually added to the
whitelist, it may be possible to execute this attack.

Users of Firefox are advised to upgrade to this updated package which
contains Firefox version 1.0.4 which is not vulnerable to these issues.

4. Solution:

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

This update is available via Red Hat Network.  To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
