Denial Of Service

KVM Kernel-based Virtual Machine is vulnerable to denial of service DoS. It is due the flaw in QEMU emulator built using 'addressspacetranslate' to map an address to a MemoryRegionSection using pcidmaread/write calls, resulting in an out-of-bounds read-write access error...

Denial Of Service (DoS)

spice-server is vulnerable to denial of service. A memory allocation flaw, leading to a heap-based buffer overflow, was found in spice's smartcard interaction, which runs under the QEMU-KVM context on the host. A user connecting to a guest VM using spice could potentially use this flaw to crash t...

Denial Of Service (DoS)

qemu-kvm-rhev is vulnerable to denial of service DoS attacks. The vulnerability exists as a use-after-free vulnerability in hw/ide/ahci.c in QEMU, when built with IDE AHCI Emulation support, allows guest OS users to cause a denial of service instance crash or possibly execute arbitrary code via a...

Denial Of Service (DoS)

qemu-kvm-rhev is vulnerable to denial of service DoS attack. The vulnerability exists as the 1 fwcfgwrite and 2 fwcfgread functions in hw/nvram/fwcfg.c in QEMU before 2.4, when built with the Firmware Configuration device emulation support, allow guest OS users with the CAPSYSRAWIO privilege to...

Denial Of Service (DoS)

qemu-kvm-rhev is vulnerable to denial of service. It was found that the QEMU's websocket frame decoder processed incoming frames without limiting resources used to process the header and the payload. An attacker able to access a guest's VNC console could use this flaw to trigger a denial of servi...

Denial Of Service (DoS)

qemu-kvm is vulnerable to denial of service. A heap buffer overflow flaw was found in the way QEMU's NE2000 NIC emulation implementation handled certain packets received over the network. A privileged user inside a guest could use this flaw to crash the QEMU instance denial of service or...

Denial Of Service (DoS)

spice-server is vulnerable to denial of service. A heap-based buffer overflow flaw was found in the way spice handled certain QXL commands related to the "surfaceid" parameter. A user in a guest could use this flaw to crash the host QEMU-KVM process or, possibly, execute arbitrary code with the...

Denial Of Service (DoS)

qemu-kvm-rhev is vulnerable to denial of service DoS attacks. The vulnerability exists through buffer overflow in the vncrefreshserversurface function in the VNC display driver in QEMU before 2.4.0.1 allows guest users to cause a denial of service heap memory corruption and process crash or...

Denial Of Service (DoS)

spice-server is vulnerable to denial of service DoS attacks. The vulnerability exists through a race condition in the workerupdatemonitorsconfig function in SPICE 0.12.4 allows a remote authenticated guest user to cause a denial of service heap-based memory corruption and QEMU-KVM crash or possib...

Denial Of Service (DoS)

qemu-kvm is vulnerable to denial of service DoS attacks. The vulnerability exists as the Floppy Disk Controller FDC in QEMU, as used in Xen 4.5.x and earlier and KVM, allows local guest users to cause a denial of service out-of-bounds write and guest crash or possibly execute arbitrary code via t...

Denial Of Service (DoS)

qemu-kvm-rhev is vulnerable to denial of service DoS attacks. The vulnerability exists as the sosendto function in slirp/udp.c in QEMU before 2.1.2 allows local users to cause a denial of service NULL pointer dereference by sending a udp packet with a value of 0 in the source port and address,...

Denial Of Service (DoS)

qemu-kvm is vulnerable to denial of service DoS attacks. The vulnerability exists as QEMU, possibly before 2.0.0, allows local users to cause a denial of service divide-by-zero error and crash via a zero value in the 1 tracks field to the seektosector function in block/parallels.c or 2 extentsize...

Denial Of Service (DoS)

qemu-kvm is vulnerable to denial of service DoS attacks. The vulnerability exists through an integer overflow issue in the qcowopen function in block/qcow.c in QEMU before 1.7.2 allows remote attackers to cause a denial of service crash via a large L2 table in a QCOW version 1 image...

Privilege Escalation

QEMU-kvm is vulnerable to privilege escalation. An unquoted search path flaw was found in the way the QEMU Guest Agent service installation was performed on Windows. Depending on the permissions of the directories in the unquoted search path, a local unprivileged user could use this flaw to have ...

Information Disclosure

qemu-kvm-rhev is vulnerable to information disclosure attacks. The vulnerability exists as qemu guest agent in Qemu 1.4.1 and earlier, as used by Xen, when started in daemon mode, uses weak permissions for certain files, which allows local users to read and write to these files...

Authorization Bypass

qemu-kvm is vulnerable to authorization bypass attacks. The vulnerability exists through a buffer overflow in the SCSI implementation in QEMU, when a SCSI controller has more than 256 attached devices, allows local users to gain privileges via a small transfer buffer in a REPORT LUNS command...

CVE-2018-16882

A use-after-free issue was found in the way the Linux kernel's KVM hypervisor processed posted interrupts when nested=1 virtualization is enabled. In nestedgetvmcs12pages, in case of an error while processing posted interrupt address, it unmaps the 'pidescpage' without resetting 'pidesc' descript...
