{"id":"USN-2409-1","summary":"qemu, qemu-kvm vulnerabilities","details":"Laszlo Ersek discovered that QEMU incorrectly handled memory in the vga\ndevice. A malicious guest could possibly use this issue to read arbitrary\nhost memory. This issue only affected Ubuntu 14.04 LTS and Ubuntu 14.10.\n(CVE-2014-3615)\n\nXavier Mehrenberger and Stephane Duverger discovered that QEMU incorrectly\nhandled certain udp packets when using guest networking. A malicious guest\ncould possibly use this issue to cause a denial of service. (CVE-2014-3640)\n\nIt was discovered that QEMU incorrectly handled parameter validation in\nthe vmware_vga device. A malicious guest could possibly use this issue to\nwrite into memory of the host, leading to privilege escalation.\n(CVE-2014-3689)\n\nIt was discovered that QEMU incorrectly handled USB xHCI controller live\nmigration. An attacker could possibly use this issue to cause a denial of\nservice, or possibly execute arbitrary code. This issue only affected\nUbuntu 14.04 LTS. (CVE-2014-5263)\n\nMichael S. Tsirkin discovered that QEMU incorrectly handled memory in the\nACPI PCI hotplug interface. A malicious guest could possibly use this issue\nto access memory of the host, leading to information disclosure or\nprivilege escalation. This issue only affected Ubuntu 14.04 LTS.\n(CVE-2014-5388)\n\nJames Spadaro discovered that QEMU incorrectly handled certain VNC\nbytes_per_pixel values. An attacker having access to a VNC console could\npossibly use this issue to cause a guest to crash, resulting in a denial of\nservice.
