CVE-2015-4478

Name of the Vulnerable Software and Affected Versions Mozilla Firefox versions prior to 40.0 Firefox ESR versions prior to 38.2

Description The issue is related to the lack of protection for certain data in Firefox browsers, allowing remote attackers to bypass the Same Origin Policy. This can be achieved via the reviver parameter to the JSON.parse method. The estimated number of potentially affected devices worldwide is not specified.

Recommendations For Mozilla Firefox versions prior to 40.0, update to version 40.0 or later. For Firefox ESR versions prior to 38.2, update to version 38.2 or later. As a temporary workaround, consider restricting the use of the JSON.parse method with the reviver parameter until a patch is available.
