The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2012:0531 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 flaw was found in the way libtasn1 decoded DER data. An attacker could     create carefully-crafted DER encoded input (such as an X.509 certificate)     that, when parsed by an application that uses libtasn1 (such as     applications using GnuTLS), could cause the application to crash.
    (CVE-2012-1569)

    A flaw was found in the way GnuTLS decrypted malformed TLS records. This     could cause a TLS/SSL client or server to crash when processing a     specially-crafted TLS record from a remote TLS/SSL connection peer.
    (CVE-2012-1573)

    An integer overflow flaw was found in the implementation of the printf     functions family. This could allow an attacker to bypass FORTIFY_SOURCE     protections and execute arbitrary code using a format string flaw in an     application, even though these protections are expected to limit the     impact of such flaws to an application abort. (CVE-2012-0864)

    Red Hat would like to thank Matthew Hall of Mu Dynamics for reporting     CVE-2012-1569 and CVE-2012-1573.

    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-2011-4128 (gnutls issue)

    CVE-2012-0879, CVE-2012-1090, and CVE-2012-1097 (kernel issues)

    CVE-2012-0884 and CVE-2012-1165 (openssl issues)

    CVE-2012-0060, CVE-2012-0061, and CVE-2012-0815 (rpm issues)

    This update also fixes the following bug:

    * The Hypervisor previously set the lro_disable option for the enic driver.
    The driver does not support this option, as a result the Hypervisor did     not correctly detect and configure the network interfaces of a Cisco M81KR     adaptor, when present. The Hypervisor has been updated and no longer sets     the invalid option for this driver. (BZ#809463)

    Users of Red Hat Enterprise Virtualization Hypervisor are advised to     upgrade to this updated package, which fixes 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 these issues but has instead relied only on the application's self-reported version number.
