Description Huzaifa S. Sidhpurwala 2013-10-28 00:39:22 EDT
Security researcher Cody Crews discovered a method to append an iframe into an embedded PDF object rendered with the chrome privileged PDF.js. This can used to bypass security restrictions to load local or chrome privileged files and objects within the embedded PDF object. This can lead to information disclosure of local system files.

In general this flaw cannot be exploited through email in the Thunderbird and Seamonkey products because scripting is disabled, but is potentially a risk in browser or browser-like contexts.
