FreeBSD : qemu -- stack buffer overflow while parsing SCSI commands (a267cd6c-b0c4-11e5-8d13-bc5ff45d0f28)

Medium Nessus Plugin ID 87701


The remote FreeBSD host is missing one or more security-related updates.


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

Qemu emulator built with the SCSI device emulation support is vulnerable to a stack-based buffer overflow issue. It could occur while parsing SCSI command descriptor block with an invalid operation code.

A privileged(CAP_SYS_RAWIO) user inside guest could use this flaw to crash the Qemu instance resulting in DoS.
