(Red Hat Issues Fix) Mozilla Firefox Multiple Vulnerabilities May Let Remote Users Execute Arbitrary Code
SecurityTracker Alert ID:  1015573
SecurityTracker URL:  http://securitytracker.com/id/1015573
CVE Reference:   CVE-2006-0292, CVE-2006-0296   (Links to External Site)
Date:  Feb 2 2006
Impact:   Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): prior to 1.5.0.1
Description:   Several vulnerabilities were reported in Mozilla Firefox. A remote user can cause arbitrary code to be executed on the target user's system.

The JavaScript engine's garbage collection processes may use temporary variables that are not properly protected (rooted) [CVE-2006-0292, CVE-2006-0293]. A remote user can create a specially crafted object containing a user-defined method that, when processed by the garbage collection process, may corrupt memory and potentially execute arbitrary code. Thunderbird may also be affected if JavaScript is enabled in mail [not the default configuration]. Igor Bukanov reported this vulnerability.

A remote user can create HTML that will dynamically change the style of an element from position:relative to position:static to trigger a memory error and potentially execute arbitrary code [CVE-2006-0294]. Version 1.5 is affected. Thunderbird version 1.5 may also be vulnerable if JavaScript is enabled in mail [not the default configuration]. Martijn Wargers reported this vulnerability.

A remote user can create HTML that invokes the QueryInterface() method of the built-in Location and Navigator objects to trigger a memory corruption error and potentially execute arbitrary code [CVE-2006-0295]. Version 1.5 is affected. Thunderbird version 1.5 may be vulnerable if JavaScript is enabled in mail [not the default configuration]. Georgi Guninski reported this vulnerability.

The XULDocument.persist() function does not properly validate the user-supplied attribute name [CVE-2006-0296]. A remote user can create specially crafted HTML that will inject XML into 'localstore.rdf'. The XML data (potentially including JavaScript commands) will be loaded when the browser next starts up. Thunderbird may be vulnerable if JavaScript is enabled [not the default configuration]. moz_bug_r_a4 reported this vulnerability.

The E4X, SVG, and Canvas features contain integer overflows [CVE-2006-0297]. A remote user may be able to execute arbitrary code. Version 1.5 is affected. Thunderbird version 1.5 may be vulnerable if JavaScript is enabled in mail [not the default configuration]. Georgi Guninski reported this vulnerability.

The XML parser may read data from locations beyond the end of the buffer [CVE-2006-0298]. As a result, the browser may crash. The vendor was not certain if it is possible for private data to be incorporated into the DOM of an XML document. Version 1.5 is affected. Johnny Stenback reported this vulnerability.

The E4X implementation's internal "AnyName" object is incorrectly available to web content [CVE-2006-0299]. Two cooperating domains could use this object as a communication channel to bypass same-origin restrictions. Version 1.5 is affected. Thunderbird version 1.5 may be vulnerable if JavaScript is enabled in mail [not the default configuration]. Brendan Eich reported this vulnerability.

Impact:   A remote user can create HTML that, when loaded by the target user, will cause arbitrary code to be executed on the target user's system with the privileges of the target user.
Solution:   Red Hat has released a fix for two of the reported vulnerabilities [CVE-2006-0292 and CVE-2006-0296].

1. Summary:

An updated firefox package that fixes several security bugs is now available.

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

3. Problem description:

Mozilla Firefox is an open source Web browser. 

Igor Bukanov discovered a bug in the way Firefox's Javascript interpreter
derefernces objects.  If a user visits a malicious web page, Firefox could
crash or execute arbitrary code as the user running Firefox. The Common
Vulnerabilities and Exposures project assigned the name CVE-2006-0292 to
this issue.

moz_bug_r_a4 discovered a bug in Firefox's XULDocument.persist() function.
A malicious web page could inject arbitrary RDF data into a user's
localstore.rdf file, which can cause Firefox to execute arbitrary
javascript when a user runs Firefox.  (CVE-2006-0296)

A denial of service bug was found in the way Firefox saves history
information. If a user visits a web page with a very long title, it is
possible Firefox will crash or take a very long time the next time it is
run. (CVE-2005-4134)

This update also fixes a bug when using XSLT to transform documents.
Passing DOM Nodes as parameters to functions expecting an xsl:param could
cause Firefox to throw an exception. 

Users of Firefox are advised to upgrade to this updated package, which
contains backported patches to correct 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.

5. Bug IDs fixed (http://bugzilla.redhat.com/):

179171 - CVE-2005-4134 Very long topic history.dat DoS
179173 - CVE-2006-0292 javascript unrooted access
