Summary
Jason Geffner discovered that QEMU incorrectly handled the virtual floppy
driver. This issue is known as VENOM. 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-2015-3456)
Daniel P. Berrange discovered that QEMU incorrectly handled VNC websockets.
A remote attacker could use this issue to cause QEMU to consume memory,
resulting in a denial of service. This issue only affected Ubuntu 14.04
LTS, Ubuntu 14.10 and Ubuntu 15.04. (CVE-2015-1779)
Jan Beulich discovered that QEMU, when used with Xen, didn't properly
restrict access to PCI command registers. A malicious guest could use this
issue to cause a denial of service. This issue only affected Ubuntu 14.04
LTS and Ubuntu 14.10. (CVE-2015-2756)
