The get_value function in epan/dissectors/packet-btatt.c in the Bluetooth Attribute (aka BT ATT) dissector in Wireshark 2.0.x before 2.0.1 uses an incorrect integer data type, which allows remote attackers to cause a denial of service (invalid write operation and application crash) via a crafted packet.
The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
