Two new bugs, dubbed Stagefright 2.0 have impacted up to one billion Android phones since 2008. When the bugs are triggered, they allow attackers to use booby-trapped audio or video files to put malicious code on the phones. This can happen even when previewing the file.

Google has announced that it will release an update this week that will fix the bugs, although when users receive the fix will depend on the brand of the phone used.
