Updated:  Jun 4 2008
Original Entry Date:  Sep 22 2005
Impact:   Denial of service via network, Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 1.0.6 and prior versions
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 a specially crafted XBM image file, that when loaded by the target user, will trigger a buffer overflow and execute arbitrary code [CVE-2005-2701]. The code will run with the privileges of the target user.

A remote user can create HTML containing specially crafted "zero-width non-joiner" Unicode sequences that, when loaded by the target user, will cause the target user's browser to crash or potentially execute arbitrary code [CVE-2005-2702].

The browser contains a flaw in making XMLHttp requests. A remote user can create specially crafted HTML that, when loaded by the target user, will spoof XMLHttpRequest headers and may be able to exploit other vulnerabilities on the target user's system or may be able to generate XMLHttp requests to other hosts [CVE-2005-2703].

A remote user can create specially crafted HTML that spoof XML objects to create an XBL binding to execute arbitrary JavaScript with elevated (chrome) permissions [CVE-2005-2704].

The JavaScript engine contains an integer overflow [CVE-2005-2705]. A remote user may be able to create HTML that, when loaded by the target user, will trigger the overflow and execute arbitrary code on the target user's system.

A remote user can create HTML that will open an 'about:' page and execute arbitrary JavaScript with elevated (chrome) privileges [CVE-2005-2706].

A remote user can create HTML that will open a new window without any user interface
components (e.g., address bar, status bar) and potentially spoof various display elements [CVE-2005-2707].

Impact:   A remote user can cause arbitrary code to be executed on the target user's system with the privileges of the target user.

A remote user can cause the target user's browser to crash.
