Detail
A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 15.10 - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS Summary: Several security issues were fixed in QEMU. Software Description: - qemu: Machine emulator and virtualizer - qemu-kvm: Machine emulator and virtualizer Details: 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 the host. (CVE-2015-8550) Qinghao Tang discovered that QEMU incorrectly handled USB EHCI emulation support. An attacker inside the guest could use this issue to cause QEMU to consume resources, resulting in a denial of service. (CVE-2015-8558) Qinghao Tang discovered that QEMU incorrectly handled the vmxnet3 device. An attacker inside the guest could use this issue to cause QEMU to consume resources, resulting in a denial of service. This issue only affected Ubuntu 14.04 LTS and Ubuntu 15.10. (CVE-2015-8567, CVE-2015-8568) Qinghao Tang discovered that QEMU incorrectly handled SCSI MegaRAID SAS HBA emulation. 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-2015-8613) Ling Liu discovered that QEMU incorrectly handled the Human Monitor Interface. A local attacker 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-2015-8619, CVE-2016-1922) David Alan Gilbert discovered that QEMU incorrectly handled the Q35 chipset emulation when performing VM guest migrations. An attacker 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-2015-8666) Ling Liu discovered that QEMU incorrectly handled the NE2000 device. An attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service. (CVE-2015-8743) It was discovered that QEMU incorrectly handled the vmxnet3 device. 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-2015-8744, CVE-2015-8745) Qinghao Tang discovered that QEMU incorrect handled IDE AHCI emulation. An attacker inside the 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-2016-1568) Donghai Zhu discovered that QEMU incorrect handled the firmware configuration device. An attacker inside the 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-2016-1714) It was discovered that QEMU incorrectly handled the e1000 device. An attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service. (CVE-2016-1981) Zuozhi Fzz discovered that QEMU incorrectly handled IDE AHCI emulation. 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 15.10. (CVE-2016-2197) Zuozhi Fzz discovered that QEMU incorrectly handled USB EHCI emulation. 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-2016-2198) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 15.10: Ubuntu 14.04 LTS: Ubuntu 12.04 LTS: After a standard system update you need to restart all QEMU virtual machines to make all the necessary changes.
