An issue was discovered on Samsung mobile devices with KK(4.4) and later software through 2015-05-13. There is a buffer overflow in datablock_write because the amount of received data is not validated. The Samsung ID is SVE-2015-4018 (December 2015).
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
