Qemu: net: out of bounds read in net_checksum_calculate()

An out-of-bounds read-access flaw was found in the QEMU emulator built with IP checksum routines. The flaw could occur when computing a TCP/UDP packet's checksum, because a QEMU function used the packet's payload length without checking against the data buffer's size. A user inside a guest could...

DEBIAN-CVE-2016-10028

The virglcmdgetcapset function in hw/display/virtio-gpu-3d.c in QEMU aka Quick Emulator built with Virtio GPU Device emulator support allows local guest OS users to cause a denial of service out-of-bounds read and process crash via a VIRTIOGPUCMDGETCAPSET command with a maximum capabilities size...

CVE-2016-10029

CVE-2016-10029 affects QEMU’s Virtio GPU Device emulator (virtio_gpu). The vulnerability is an out-of-bounds read in the virtio_gpu_set_scanout handler when a VIRTIO_GPU_CMD_SET_SCANOUT command uses a scanout id larger than num_scanouts. This local-privilege level issue can cause a guest user to ...

CVE-2016-10028

CVE-2016-10028 affects QEMU with Virtio GPU Device emulator support. The flaw is in virgl_cmd_get_capset (hw/display/virtio-gpu-3d.c) where processing a VIRTIO_GPU_CMD_GET_CAPSET with a max capabilities size of 0 allows an unprivileged local guest user to trigger an out-of-bounds read, crash the ...
