Prasad J Pandit, Red Hat Product Security Team, reports:
Qemu emulator built with the Human Monitor Interface(HMP) support
is vulnerable to an OOB write issue. It occurs while processing
'sendkey' command in hmp_sendkey routine, if the command argument is
longer than the 'keyname_buf' buffer size.
A user/process could use this flaw to crash the Qemu process
instance resulting in DoS.
