Qinghao Tang discovered that QEMU incorrectly handled receiving certain
packets in the NE2000 network 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. (CVE-2015-5279)
Qinghao Tang discovered that QEMU incorrectly handled transmit descriptor
data when sending network packets. A malicious guest could use this issue
to cause the QEMU process to hang, resulting in a denial of service.
(CVE-2015-6815)
Qinghao Tang discovered that QEMU incorrectly handled ATAPI command
permissions. A malicious guest could use this issue to cause the QEMU
process to crash, resulting in a denial of service. (CVE-2015-6855)
