Description

Prasad J Pandit, Red Hat Product Security Team, reports :

Qemu emulator built with the SCSI MegaRAID SAS HBA emulation support is vulnerable to a stack-based buffer overflow issue. It occurs while processing the SCSI controller's CTRL_GET_INFO command. A privileged guest user could use this flaw to crash the Qemu process instance resulting in DoS.

Solution
