Description

Matt Tait discovered that QEMU incorrectly handled PIT emulation. In a
non-default configuration, a malicious guest could use this issue to cause
a denial of service, or possibly execute arbitrary code on the host as the
user running the QEMU process. In the default installation, when QEMU is
used with libvirt, attackers would be isolated by the libvirt AppArmor
profile. (CVE-2015-3214)

Kevin Wolf discovered that QEMU incorrectly handled processing ATAPI
commands. A malicious guest could use this issue to cause a denial of
service, or possibly execute arbitrary code on the host as the user running
the QEMU process. In the default installation, when QEMU is used with
libvirt, attackers would be isolated by the libvirt AppArmor profile.
(CVE-2015-5154)

Zhu Donghai discovered that QEMU incorrectly handled the SCSI driver. A
malicious guest could use this issue to cause a denial of service, or
possibly execute arbitrary code on the host as the user running the QEMU
process. In the default installation, when QEMU is used with libvirt,
attackers would be isolated by the libvirt AppArmor profile. This issue
only affected Ubuntu 15.04. (CVE-2015-5158)
