Heap-based buffer overflow in the GIF library in the WebKit framework for Google Android SDK m3-rc37a and earlier allows remote attackers to execute arbitrary code via a crafted GIF file whose logical screen height and width are different than the actual height and width.
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.
