Subject: CVE-2018-19665 Qemu: bt: integer overflow in Bluetooth routines
allows memory corruption
Hello,
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.
