Mozilla Firefox Multiple Flaws Let Remote Users Execute Arbitrary Code, Conduct Cross-Site Request Forgery Attacks, and Obtain Potentially Sensitive Information
SecurityTracker Alert ID:  1031533
SecurityTracker URL:  http://securitytracker.com/id/1031533
CVE Reference:   CVE-2014-8634, CVE-2014-8635, CVE-2014-8636, CVE-2014-8637, CVE-2014-8638, CVE-2014-8639, CVE-2014-8640, CVE-2014-8641, CVE-2014-8642, CVE-2014-8643   (Links to External Site)
Updated:  Jan 14 2015
Original Entry Date:  Jan 14 2015
Impact:   Disclosure of system information, Disclosure of user information, Execution of arbitrary code via network, Modification of authentication information, Modification of user information, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): prior to 35.0
Description:   Multiple 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 conduct cross-site request forgery attacks. A remote user can obtain potentially sensitive information.

A remote user can create specially crafted HTML that, when loaded by the target user, will execute arbitrary code on the target system [CVE-2014-8634, CVE-2014-8635].

A remote user can create a specially crafted bitmap image that, when rendered by the target user's browser via a 'canvas' element, will access uninitialized memory [CVE-2014-8637].

The navigator.sendBeacon() function does not honor the cross-origin resource sharing (CORS) specification. A remote user can exploit this to conduct cross-site request forgery attacks [CVE-2014-8638].

A remote Web Proxy can return an HTTP 407 Proxy Authentication response with a specially crafted Set-Cookie header value to inject cookies and conduct session-fixation attacks [CVE-2014-8639].

A remote user can create specially crafted Document Object Model (DOM) objects with specific properties that can bypass XrayWrappers to gain elevated privileges on the target user's system [CVE-2014-8636].

A remote user can create specially crafted content that manipulates Web Audio to be able to access a small block of memory via an uninitialized pointer [CVE-2014-8640].

A remote user can trigger a read-after-free memory error in the handling of tracks in WebRTC [CVE-2014-8641].

Delegated Online Certificate Status Protocol (OCSP) responder certificates do not recognize the id-pkix-ocsp-nocheck extension. A user may be able to connect to a web site that has a revoked certificate [CVE-2014-8642].

A remote user that can exploit a separate flaw in the Gecko Media Plugin (GMP) can escape the sandbox on Windows-based systems [CVE-2014-8643].

Christian Holler, Patrick McManus, Christoph Diehl, Gary Kwong, Jesse Ruderman, Byron Campen, Terrence Cole, Nils Ohlmeier, Muneaki Nishimura, Xiaofeng Zheng of the Blue Lotus Team at Tsinghua University, Google security researcher Michal Zalewski, Holger Fuhrmannek, Mitchell Harper, Nils, Brian Smith, and Mozilla developer Bobby Holley 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.

A remote user can take actions on the site acting as the target user.

A remote user can conduct session fixation attacks.

A remote user can obtain potentially sensitive information.

Solution:   The vendor has issued a fix (35.0).
