The structured-clone implementation in Mozilla Firefox before 34.0 and SeaMonkey before 2.31 does not properly interact with XrayWrapper property filtering, which allows remote attackers to bypass intended DOM object restrictions by leveraging property availability after XrayWrapper removal.

Versions of Mozilla Firefox ESR earlier than 31.3 are unpatched for the following vulnerabilities :

 - Security Bypass that can be leveraged when processing specially crafted Chrome-based CSS stylesheets with improperly declared namespaces. (CVE-2014-1589)
 - Information Disclosure due to the way Content Security Policy leaks data through violation reports. (CVE-2014-1591)
 - Multiple Unspecified Memory Corruption Vulnerabilities. (CVE-2014-1587)(CVE-2014-1588)
 - Multiple Local Information Disclosure Vulnerabilities requiring interactive access to exploit. (CVE-2014-1595)
 - Security Vulnerability due to bad casting from 'BasicThebesLayer' to 'BasicContainerLayer'. (CVE-2014-1594)
 - Denial of Service Vulnerability can occur when passing a js object to 'XMLHttpRequest' that mimics an input stream. (CVE-2014-1590)
 - Use After Free Memory Corruption Vulnerability when creating a second root element during the parsing of an HTML5 document which contains 'document.open()'. (CVE-2014-1592)
 - Buffer Overflow Vulnerability when handling specially crafted media content. (CVE-2014-1593)
 - A flaw exists and is triggered as 'XrayWrappers' filter objects are not properly validated when stored in the program. This may allow a context-dependent attacker to bypass security protection mechanisms. (CVE-2014-8632)

The remote host is affected by the vulnerability described in GLSA-201504-01 (Mozilla Products: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Firefox, Thunderbird,       and SeaMonkey. Please review the CVE identifiers referenced below for       details.
  Impact :

    A remote attacker could entice a user to view a specially crafted web       page or email, possibly resulting in execution of arbitrary code or a       Denial of Service condition. Furthermore, a remote attacker may be able       to perform Man-in-the-Middle attacks, obtain sensitive information, spoof       the address bar, conduct clickjacking attacks, bypass security       restrictions and protection mechanisms,  or have other unspecified       impact.
  Workaround :

    There are no known workarounds at this time.

The version of Firefox installed on the remote Windows host is a version prior to 34.0. It is, therefore, affected by the following vulnerabilities :

  - A security bypass vulnerability exists due to the     'XrayWrappers' filter not properly validating object     properties. This allows a remote attacker to bypass     security protection mechanisms to access protected     objects. (CVE-2014-8631)

  - A security bypass vulnerability exists due to Chrome     Object Wrappers (COW) being passed as native interfaces.
    This allows a remote attacker to access normally     protected objects. (CVE-2014-8632)

  - A remote code execution vulnerability exists in Mozilla     Network Security Services (NSS) due to a flaw in     'quickder.c' that is triggered when handling PKCS#1     signatures during the decoding of ASN.1 DER.
    (CVE-2014-1569)

  - Multiple memory safety flaws exist within the browser     engine. Exploiting these, an attacker can cause a denial     of service or execute arbitrary code. (CVE-2014-1587,     CVE-2014-1588)

  - A security bypass vulnerability exists due improper     declaration of chrome accessible CSS primary namespaces     allowing for XML Binding Language (XBL) bindings to be     triggered remotely. (CVE-2014-1589)

  - A denial of service vulnerability exists due to     improper parsing of a JavaScript object to the     XMLHttpRequest API which can result in a crash.
    (CVE-2014-1590)

  - An information disclosure vulnerability exists due to     Content Security Policy (CSP) violation reports     triggered by a redirect not properly removing path     information which can reveal sensitive information.
    Note that this only affects Firefox 33. (CVE-2014-1591)

  - A use-after-free error exists due the creation of a     second XML root element when parsing HTML written to a     document created with 'document.open()' function which     can result in arbitrary code execution. (CVE-2014-1592)

  - A buffer overflow vulnerability exists in the     'mozilla::FileBlockCache::Read' function when parsing     media which can result in arbitrary code execution.
    (CVE-2014-1593)

  - A casting error exists when casting from the     'BasicThebesLayer' layer to the 'BasicContainerLayer'     layer which can result in arbitrary code execution.
    (CVE-2014-1594)

The version of Firefox installed on the remote Mac OS X host is a version prior to 34.0. It is, therefore, affected by the following vulnerabilities :
