If you though the bluster of the first Stagefright vulnerability had blown over, think again.
A set of two new vulnerabilities, dubbed Stagefright 2.0, could allow an attacker to exploit a weakness in how Android processes audio (MP3) and video (MP4) files, which can be used to install malware.
The scope of the flaw isn't thought as wide as the first Stagefright vulnerability. The second flaw affects devices mostly running Android 5.0 "Lollipop" and later. The researchers said in a blog post that some Android phones running an older components may also "be impacted."
