## Description

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 virtio\_blk\_handle\_write function or (2) read request
to the virtio\_blk\_handle\_read function that is not properly aligned.
