Mozilla Firefox Multiple Vulnerabilities May Let Remote Users Execute Arbitrary Code
SecurityTracker Alert ID:  1015570
SecurityTracker URL:  http://securitytracker.com/id/1015570
CVE Reference:   CVE-2006-0292, CVE-2006-0293, CVE-2006-0294, CVE-2006-0295, CVE-2006-0296, CVE-2006-0297, CVE-2006-0298, CVE-2006-0299   (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:   The vendor has issued a fixed version (1.5.0.1).
