CVE-2015-7549 [MEDIUM] QEMU vulnerabilities
Title: QEMU vulnerabilities
Summary: Several security issues were fixed in QEMU.
Qinghao Tang discovered that QEMU incorrectly handled PCI MSI-X support. An
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
and Ubuntu 15.10. (CVE-2015-7549)
Lian Yihan discovered that QEMU incorrectly handled the VNC server. A
remote attacker could use this issue to cause QEMU to crash, resulting in a
denial of service. (CVE-2015-8504)
Felix Wilhelm discovered a race condition in the Xen paravirtualized
drivers which can cause double fetch vulnerabilities. An attacker in the
paravirtualized guest could exploit this flaw to cause a denial of service
(crash the host) or potentially execute arbitrary code on th
