"The remote Redhat Enterprise Linux 6 host has a package installed that is affected by a vulnerability as referenced in
the RHSA-2013:1076 advisory.

    The rhev-hypervisor6 package provides a Red Hat Enterprise Virtualization
    Hypervisor ISO disk image. The Red Hat Enterprise Virtualization Hypervisor
    is a dedicated Kernel-based Virtual Machine (KVM) hypervisor. It includes
    everything necessary to run and manage virtual machines: A subset of the
    Red Hat Enterprise Linux operating environment and the Red Hat Enterprise
    Virtualization Agent.

    Note: Red Hat Enterprise Virtualization Hypervisor is only available for
    the Intel 64 and AMD64 architectures with virtualization extensions.

    It was discovered that the fix for the CVE-2013-1619 issue released via
    RHSA-2013:0636 introduced a regression in the way GnuTLS decrypted TLS/SSL
    encrypted records when CBC-mode cipher suites were used. A remote attacker
    could possibly use this flaw to crash a server or client application that
    uses GnuTLS. (CVE-2013-2116)

    This updated package provides updated components that include fixes for
    various security issues. These issues have no security impact on Red Hat
    Enterprise Virtualization Hypervisor itself, however. The security fixes
    included in this update address the following CVE numbers:

    CVE-2013-2174 (curl issue)

    CVE-2012-6548, CVE-2013-0914, CVE-2013-1848, CVE-2013-2128, CVE-2013-2634,
    CVE-2013-2635, CVE-2013-2852, CVE-2013-3222, CVE-2013-3224, CVE-2013-3225,
    and CVE-2013-3301 (kernel issues)

    CVE-2002-2443 (krb5 issue)

    CVE-2013-1950 (libtirpc issue)

    Upgrade Note: If you upgrade the Red Hat Enterprise Virtualization
    Hypervisor through the 3.2 Manager administration portal, the Host may
    appear with the status of Install Failed. If this happens, place the host
    into maintenance mode, then activate it again to get the host back to an
    Up state.

    This update also contains the fixes from the following errata:

    * ovirt-node: RHBA-2013:1077

    Users of the Red Hat Enterprise Virtualization Hypervisor are advised to
    upgrade to this updated package, which corrects these issues.

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

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
