The remote Redhat Enterprise Linux 6 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2015:0126 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.

    A heap-based buffer overflow was found in glibc's
    __nss_hostname_digits_dots() function, which is used by the gethostbyname()     and gethostbyname2() glibc function calls. A remote attacker able to make     an application call either of these functions could use this flaw to     execute arbitrary code with the permissions of the user running the     application. (CVE-2015-0235)

    A race condition flaw was found in the way the Linux kernel's KVM subsystem     handled PIT (Programmable Interval Timer) emulation. A guest user who has     access to the PIT I/O ports could use this flaw to crash the host.
    (CVE-2014-3611)

    A flaw was found in the way OpenSSL handled fragmented handshake packets.
    A man-in-the-middle attacker could use this flaw to force a TLS/SSL server     using OpenSSL to use TLS 1.0, even if both the client and the server     supported newer protocol versions. (CVE-2014-3511)

    A memory leak flaw was found in the way an OpenSSL handled failed session     ticket integrity checks. A remote attacker could exhaust all available     memory of an SSL/TLS or DTLS server by sending a large number of invalid     session tickets to that server. (CVE-2014-3567)

    It was found that the Linux kernel's KVM subsystem did not handle the VM     exits gracefully for the invept (Invalidate Translations Derived from EPT)     and invvpid (Invalidate Translations Based on VPID) instructions. On hosts     with an Intel processor and invept/invppid VM exit support, an unprivileged     guest user could use these instructions to crash the guest. (CVE-2014-3645,     CVE-2014-3646)

    Red Hat would like to thank Qualys for reporting the CVE-2015-0235 issue,     Lars Bull of Google for reporting the CVE-2014-3611 issue, and the Advanced     Threat Research team at Intel Security for reporting the CVE-2014-3645 and     CVE-2014-3646 issues.

    Users of the Red Hat Enterprise Virtualization Hypervisor are advised to     upgrade to this updated package.

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.
