Stagefright flaw in Android exploits how Android’s MMS (Multimedia Messages) system automatically downloads MMS content (e.g. video) to be read / cached locally, without any user interaction. This automatic reading of the MMS content allows attackers to embed their virus / trojan payload into a video which will automatically be run by Android’s Content Provider / Stagefright system.
