"The remote Red Hat host is missing one or more security updates for kernel.");
  script_set_attribute(attribute:"description", value:
"The remote Redhat Enterprise Linux 5 host has packages installed that are affected by multiple vulnerabilities as
referenced in the RHSA-2014:0740 advisory.

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

    * A flaw was found in the way the Linux kernel's floppy driver handled user
    space provided data in certain error code paths while processing FDRAWCMD
    IOCTL commands. A local user with write access to /dev/fdX could use this
    flaw to free (using the kfree() function) arbitrary kernel memory.
    (CVE-2014-1737, Important)

    * It was found that the Linux kernel's floppy driver leaked internal kernel
    memory addresses to user space during the processing of the FDRAWCMD IOCTL
    command. A local user with write access to /dev/fdX could use this flaw to
    obtain information about the kernel heap arrangement. (CVE-2014-1738, Low)

    Note: A local user with write access to /dev/fdX could use these two flaws
    (CVE-2014-1737 in combination with CVE-2014-1738) to escalate their
    privileges on the system.

    * A NULL pointer dereference flaw was found in the rds_ib_laddr_check()
    function in the Linux kernel's implementation of Reliable Datagram Sockets
    (RDS). A local, unprivileged user could use this flaw to crash the system.
    (CVE-2013-7339, Moderate)

    Red Hat would like to thank Matthew Daley for reporting CVE-2014-1737 and
    CVE-2014-1738.

    This update also fixes the following bugs:

    * A bug in the futex system call could result in an overflow when passing
    a very large positive timeout. As a consequence, the FUTEX_WAIT operation
    did not work as intended and the system call was timing out immediately.
    A backported patch fixes this bug by limiting very large positive timeouts
    to the maximal supported value. (BZ#1091832)

    * A new Linux Security Module (LSM) functionality related to the setrlimit
    hooks should produce a warning message when used by a third party module
    that could not cope with it. However, due to a programming error, the
    kernel could print this warning message when a process was setting rlimits
    for a different process, or if rlimits were modified by another than the
    main thread even though there was no incompatible third party module. This
    update fixes the relevant code and ensures that the kernel handles this
    warning message correctly. (BZ#1092869)

    * Previously, the kernel was unable to detect KVM on system boot if the
    Hyper-V emulation was enabled. A patch has been applied to ensure that
    both KVM and Hyper-V hypervisors are now correctly detected during system
    boot. (BZ#1094152)

    * A function in the RPC code responsible for verifying whether cached
    credentials match the current process did not perform the check correctly.
    The code checked only whether the groups in the current process
    credentials appear in the same order as in the cached credentials but did
    not ensure that no other groups are present in the cached credentials. As
    a consequence, when accessing files in NFS mounts, a process with the same
    UID and GID as the original process but with a non-matching group list
    could have been granted an unauthorized access to a file, or under certain
    circumstances, the process could have been wrongly prevented from
    accessing the file. The incorrect test condition has been fixed and the
    problem can no longer occur. (BZ#1095062)

    * When being under heavy load, some Fibre Channel storage devices, such as
    Hitachi and HP Open-V series, can send a logout (LOGO) message to the
    host system. However, due to a bug in the lpfc driver, this could result
    in a loss of active paths to the storage and the paths could not be
    recovered without manual intervention. This update corrects the lpfc
    driver to ensure automatic recovery of the lost paths to the storage in
    this scenario. (BZ#1096061)

    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.");
