The decoder_peek_si_internal function in vp9/vp9_dx_iface.c in libvpx in mediaserver in Android 4.x before 4.4.4, 5.0.x before 5.0.2, 5.1.x before 5.1.1, 6.x before 2016-09-01, and 7.0 before 2016-09-01 allows remote attackers to cause a denial of service (buffer over-read, and device hang or reboot) via a crafted media file, aka internal bug 30013856.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
