(Red Hat Issues Fix) Mozilla Firefox Bugs in JavaScript Engine and Browser Engine May Let Remote Users Execute Arbitrary Code
SecurityTracker Alert ID:  1022377
SecurityTracker URL:  http://securitytracker.com/id/1022377
CVE Reference:   CVE-2009-1392, CVE-2009-1832, CVE-2009-1833   (Links to External Site)
Date:  Jun 12 2009
Impact:   Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): prior to 3.0.11
Description:   Several vulnerabilities were reported in Mozilla Firefox. A remote user can cause arbitrary code to be executed on the target user's system.

A remote user can create specially crafted HTML that, when loaded by the target user, will trigger memory corruption errors and execute arbitrary code on the target system. The code will run with the privileges of the target user.

Mozilla SeaMonkey is also affected.

Bob Clary, Jesse Ruderman, Alexander Sack, Bret McMillan, Tomeo Vizoso, Matt McCutchen, Martijn Wargers, Adam Hauner, and Igor Bukanov reported these vulnerabilities.
Impact:   A remote user can create HTML that, when loaded by the target user, will execute arbitrary code on the target user's system.
Solution:   Red Hat has released a fix.

The Red Hat advisory is available at:

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 as the user running Firefox.
(CVE-2009-1392, CVE-2009-1832, CVE-2009-1833, CVE-2009-1837, CVE-2009-1838,
CVE-2009-1841)

Multiple flaws were found in the processing of malformed, local file
content. If a user loaded malicious, local content via the file:// URL, it
was possible for that content to access other local data. (CVE-2009-1835,
CVE-2009-1839)

A script, privilege elevation flaw was found in the way Firefox loaded XML
User Interface Language (XUL) scripts. Firefox and certain add-ons could
load malicious content when certain policy checks did not happen.
(CVE-2009-1840)

A flaw was found in the way Firefox displayed certain Unicode characters in
International Domain Names (IDN). If an IDN contained invalid characters,
they may have been displayed as spaces, making it appear to the user that
they were visiting a trusted site. (CVE-2009-1834)

A flaw was found in the way Firefox handled error responses returned from
proxy servers. If an attacker is able to conduct a man-in-the-middle attack
against a Firefox instance that is using a proxy server, they may be able
to steal sensitive information from the site the user is visiting.
(CVE-2009-1836)

For technical details regarding these flaws, refer to the Mozilla security
advisories for Firefox 3.0.11. 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 3.0.11, 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 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
