The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2016:1204 advisory.

    The Simple Protocol for Independent Computing Environments (SPICE) is a remote display protocol for     virtual environments. SPICE users can access a virtualized desktop or server from the local system or any     system with network access to the server. SPICE is used in Red Hat Enterprise Linux for viewing     virtualized guests running on the Kernel-based Virtual Machine (KVM) hypervisor or on Red Hat Enterprise     Virtualization Hypervisors.

    Security Fix(es):

    * 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. (CVE-2016-0749)

    * A memory access flaw was found in the way spice handled certain guests using crafted primary surface     parameters. A user in a guest could use this flaw to read from and write to arbitrary memory locations on     the host. (CVE-2016-2150)

    The CVE-2016-0749 issue was discovered by Jing Zhao (Red Hat) and the CVE-2016-2150 issue was discovered     by Frediano Ziglio (Red Hat).

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
