"Michael S. Tsirkin, Anthony Liguori, and Michael Roth discovered

CVE-2014-0182, CVE-2014-3461)

Kevin Wolf, Stefan Hajnoczi, Fam Zheng, Jeff Cody, Stefan Hajnoczi,
and others discovered multiple issues in the QEMU block drivers. An
attacker able to modify disk images could use these issues to cause a
denial of service, or possibly execute arbitrary code. (CVE-2014-0142,
CVE-2014-0143, CVE-2014-0144, CVE-2014-0145, CVE-2014-0146,
CVE-2014-0147, CVE-2014-0222, CVE-2014-0223)

It was discovered that QEMU incorrectly handled certain PCIe bus
hotplug operations. A malicious guest could use this issue to crash
the QEMU host, resulting in a denial of service. (CVE-2014-3471).
