A day before news broke that Russian hackers were able to access part of the Joint Chief’s email at the Pentagon, a Firefox user found a vulnerability that could send your sensitive files to a server in the Ukraine.
Here’s an easy fix
Mozilla said it is not sure where the ad came from originally and that products that don’t use the PDF Viewer are not vulnerable.
One issue is that the program leaves no trace that it has been run on a machine.
So how can you fix the flaw?
The hackers were looking for FTP configuration files, subversion, .purple among other account information on Windows systems. On Linux, the flaw looked for global configuration files and user directories, The Next Web reported. Macs were not targeted, as far as experts found.
Mozilla says you need to update to the latest version: Firefox 39.0.3 or Firefox ESR 38.1.1. The updates have the latest security features and fix the flaw.
