libs/gui/BufferQueueConsumer.cpp in mediaserver in Android 4.x before 4.4.4, 5.0.x before 5.0.2, 5.1.x before 5.1.1, and 6.x before 2016-04-01 does not check for the android.permission.DUMP permission, which allows attackers to obtain sensitive information, and consequently bypass an unspecified protection mechanism, via a dump request, as demonstrated by obtaining Signature or SignatureOrSystem access, aka internal bug 27046057.
