Google has come out with its second security patch update for Android in 2016, this time patching 13 vulnerabilities in the mobile device operating system. Five of the vulnerabilities are rated by Google as having critical severity.

Of the five critical vulnerabilities patched by Google, two (CVE-2016-0803 and CVE-2016-0804) are remote code execution vulnerabilities in Android’s mediaserver. The Android mediaserver has been the focus of Google security patches ever since the Stagefright flaw was first exposed in July 2015. As was the case in the January Android update, the new mediaserver flaws are not specifically in the libstagefright library, but they are in the same general area of Android’s architecture.
