CVE-2015-0816

Name of the Vulnerable Software and Affected Versions Mozilla Firefox versions prior to 37.0 Firefox ESR versions 31.x prior to 31.6 Thunderbird versions prior to 31.6

Description The issue is related to the incorrect restriction of resource: URLs, allowing a remote attacker to execute arbitrary JavaScript code with chrome privileges by bypassing the Same Origin Policy. This can be achieved through a resource: URL associated with PDF.js. The estimated number of potentially affected devices is not specified.

Recommendations For Mozilla Firefox versions prior to 37.0, update to version 37.0 or later. For Firefox ESR versions 31.x prior to 31.6, update to version 31.6 or later. For Thunderbird versions prior to 31.6, update to version 31.6 or later. As a temporary workaround, consider restricting access to the resource: URL associated with PDF.js to minimize the risk of exploitation.
