Red Hat Security Advisory 2016-1205-01 – The Simple Protocol for Independent Computing Environments is a remote display system built for virtual environments which allows the user to view a computing ‘desktop’ environment not only on the machine where it is running, but from anywhere on the Internet and from a wide variety of machine architectures. Security Fix: 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 the QEMU-KVM process or execute arbitrary code with the privileges of the host’s QEMU-KVM process.
