SeaMonkey < 2.13.2 Multiple Vulnerabilities

Versions of SeaMonkey prior to 2.13.2 are potentially affected by the following security issues :

• The true value of ‘window.location’ can be shadowed by user content through the use of the ‘valueOf’ method, which can be combined with some plugins to perform cross-site scripting attacks. (CVE-2012-4194)
• The ‘CheckURL’ function of ‘window.location’ can be forced to return the wrong calling document and principal, allowing a cross-site scripting attack. (CVE-2012-4195)
• It is possible to use property injection by prototype to bypass security wrapper protections on the ‘Location’ object, allowing the cross-origin reading of the ‘Location’ object. (CVE-2012-4196)
