Updates downloaded from Google Play store directly does not have to contain such malicious apps but updates downloaded from other sources may contain malicious apps where a hacker can use this vulnerability to gain access over the device.

Already, Bluebox has reported the vulnerability in the month of February of this year to Google. Now, the internet giant, Google is working on the vulnerability so that they could release a patch for fixing this vulnerability on Android devices or fix the vulnerability on upcoming Android versions.

Samsung Galaxy S4, which was launched recently does not seem to contain this type of vulnerability as the company fixed vulnerability while they released the smartphone.

Statistically, this vulnerability could affect more than 900 million devices. A hacker could easily provide such malicious updates via email or with the help of any other sources.
