'Quadrooter' security flaws said to affect over 900 million Android devices - CNET

Four newly-discovered vulnerabilities found in Android phones and tablets that ship with a Qualcomm chip could allow an attacker to take complete control of an affected device.

The set of vulnerabilities, dubbed "Quadrooter," affects over 900 million phone and tablets, according to Check Point researchers who discovered the flaws.

An attacker would have to trick a user into installing a malicious app, which wouldn't require any special permissions.

If successfully exploited, an attacker can gain root access, which gives the attacker full access to an affected Android device, its data, and its hardware -- including its camera and microphone.
