Researchers from Trend Micro discovered a new critical vulnerability in the Android mobile OS that can be exploited to crash mobile devices. The vulnerability is caused by an integer overflow when the mediaserver service parses an MKV file. An attacker can trigger the Android vulnerability by sending a malformed video file using the Matroska container. The attacker can exploit the flaw to make the targeted smartphone inoperable and silent, the attack completely mute the device making the user interface unresponsive. The flaw potentially affects half of the Android devices that are running the flawed versions.”]
