The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2014:0328 advisory.

    The kernel packages contain the Linux kernel, the core of any Linux     operating system.

    * A flaw was found in the way the get_rx_bufs() function in the vhost_net     implementation in the Linux kernel handled error conditions reported by the     vhost_get_vq_desc() function. A privileged guest user could use this flaw     to crash the host. (CVE-2014-0055, Important)

    * A flaw was found in the way the Linux kernel processed an authenticated     COOKIE_ECHO chunk during the initialization of an SCTP connection. A remote     attacker could use this flaw to crash the system by initiating a specially     crafted SCTP handshake in order to trigger a NULL pointer dereference on     the system. (CVE-2014-0101, Important)

    * A flaw was found in the way the Linux kernel's CIFS implementation     handled uncached write operations with specially crafted iovec structures.
    An unprivileged local user with access to a CIFS share could use this flaw     to crash the system, leak kernel memory, or, potentially, escalate their     privileges on the system. Note: the default cache settings for CIFS mounts     on Red Hat Enterprise Linux 6 prohibit a successful exploitation of this     issue. (CVE-2014-0069, Moderate)

    * A heap-based buffer overflow flaw was found in the Linux kernel's cdc-wdm     driver, used for USB CDC WCM device management. An attacker with physical     access to a system could use this flaw to cause a denial of service or,     potentially, escalate their privileges. (CVE-2013-1860, Low)

    Red Hat would like to thank Nokia Siemens Networks for reporting     CVE-2014-0101, and Al Viro for reporting CVE-2014-0069.

    This update also fixes several bugs. Documentation for these changes will     be available shortly from the Technical Notes document linked to in the     References section.

    All kernel users are advised to upgrade to these updated packages, which     contain backported patches to correct these issues. The system must be     rebooted for this update to take effect.

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.
