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.
