Heap overflow

Multiple heap-based buffer overflows in the virtio-blk driver hw/virtio-blk.c in qemu-kvm 0.14.0 allow local guest users to cause a denial of service guest crash and possibly gain privileges via a 1 write request to the virtioblkhandlewrite function or 2 read request to the virtioblkhandleread...

Authentication flaw

qemu-kvm before 0.11.0 disables VNC authentication when the password is cleared, which allows remote attackers to bypass authentication and establish VNC sessions...

CVE-2011-1751

CVE-2011-1751 affects qemu-kvm’s PIIX4 Power Management emulation (hw/acpi_piix4.c). The vulnerability arises because pciej_write does not verify whether a device is hotpluggable before unplugging the PCI-ISA bridge, enabling a privileged guest to crash the guest (denial of service) and potential...

CVE-2011-2212

CVE-2011-2212 describes a buffer overflow in the virtio subsystem of qemu-kvm up to version 0.14.0 and earlier. A privileged guest user could crash the guest or gain host privileges via a crafted indirect descriptor in virtqueue in/out requests. The connected advisories (RHSA-2011:0919, ELSA-2011...

CVE-2011-1751

The pciejwrite function in hw/acpipiix4.c in the PIIX4 Power Management emulation in qemu-kvm does not check if a device is hotpluggable before unplugging the PCI-ISA bridge, which allows privileged guest users to cause a denial of service guest crash and possibly execute arbitrary code by sendin...

CVE-2011-0011

CVE-2011-0011 affects qemu-kvm prior to 0.11.0, where clearing the VNC password disables authentication and allows a remote user to open VNC sessions without authentication. Red Hat, Oracle Linux, Scientific Linux and MiracleLinux advisories from 2011 document the fix as a backported patch; remed...

CVE-2011-2512

CVE-2011-2512 affects qemu-kvm up to version 0.14.0 where virtio_queue_notify did not validate the virtqueue index, allowing a guest user to crash the guest (DoS) and potentially execute arbitrary code using a negative value in the Virtio Header Queue Notify field due to a signed comparison bypas...

CVE-2011-1750

CVE-2011-1750 affects qemu-kvm 0.14.0 with heap-based buffer overflows in virtio-blk (hw/virtio-blk.c) allowing a privileged guest user to crash the guest or potentially gain host privileges via unaligned read/write requests. Connected advisories confirm affected environments (e.g., RHSA-2011:053...

CVE-2011-1750

Multiple heap-based buffer overflows in the virtio-blk driver hw/virtio-blk.c in qemu-kvm 0.14.0 allow local guest users to cause a denial of service guest crash and possibly gain privileges via a 1 write request to the virtioblkhandlewrite function or 2 read request to the virtioblkhandleread...
