Descriptions

The sdhci_sdma_transfer_multi_blocks function in hw/sd/sdhci.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (out-of-bounds heap access and crash) or execute arbitrary code on the QEMU host via vectors involving the data transfer length.

La función sdhci_sdma_transfer_multi_blocks en hw/sd/sdhci.c en QEMU (también conocido como Quick Emulator) permite a usuarios locales privilegiados del SO invitado provocar una denegación de servicio (acceso de memoria dinámica fuera de límite y caída) o ejecutar código arbitrario en el host de QEMU a través de vectores que involucran la longitud de la transferencia de datos.

Zhenhao Hong discovered that QEMU incorrectly handled the Virtio GPU 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 16.04 LTS and Ubuntu 16.10. Li Qiang discovered that QEMU incorrectly handled the 6300esb watchdog. A privileged attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service. Various other issues were also addressed.
