An integer overflow resulting in memory corruption issue was found in various Bluetooth functions. It could occur in routines wherein 'len' parameter is a 'signed int' which subsequently converts to an unsigned integer resulting in memcpy() copying large amounts of memory. A user inside guest could use this flaw to crash the Qemu process resulting in DoS.
