CVE-2016-5403 [MEDIUM] QEMU vulnerabilities
Title: QEMU vulnerabilities
Summary: Several security issues were fixed in QEMU.
Zhenhao Hong discovered that QEMU incorrectly handled the Virtio module. A
privileged attacker inside the guest could use this issue to cause QEMU to
consume resources, resulting in a denial of service. (CVE-2016-5403)
Li Qiang discovered that QEMU incorrectly handled VMWARE VMXNET3 network
card emulation support. A privileged attacker inside the guest could use
this issue to cause QEMU to crash, resulting in a denial of service. This
issue only affected Ubuntu 14.04 LTS, Ubuntu 16.04 LTS and Ubuntu 16.10.

Qemu: scsi: mptsas: OOB access when freeing MPTSASRequest object
The mptsas_process_scsi_io_request function in QEMU (aka Quick Emulator), when built with LSI SAS1068 Host Bus emulation support, allows local guest OS administrators to cause a denial of service (out-of-bounds write and QEMU process crash) via vectors involving MPTSASRequest objects.
A flaw was found in the Quick Emulator(QEMU) built with LSI SAS1068 Host Bus emulation support, where it is vulnerable to an invalid memory-access issue. The flaw could occur while processing SCSI IO requests in the mptsas_process_scsi_io_request routine. A privileged user inside the guest could use this flaw to crash the QEMU-process instance on the host (denial of service).
