"The remote Oracle Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the
ELSA-2013-11661 advisory.

  - The HP Smart Array controller disk-array driver and Compaq SMART2 controller disk-array driver in the
    Linux kernel through 3.9.4 do not initialize certain data structures, which allows local users to obtain
    sensitive information from kernel memory via (1) a crafted IDAGETPCIINFO command for a /dev/ida device,
    related to the ida_locked_ioctl function in drivers/block/cpqarray.c or (2) a crafted CCISS_PASSTHRU32
    command for a /dev/cciss device, related to the cciss_ioctl32_passthru function in drivers/block/cciss.c.
    (CVE-2013-2147)

  - The mmc_ioctl_cdrom_read_data function in drivers/cdrom/cdrom.c in the Linux kernel through 3.10 allows
    local users to obtain sensitive information from kernel memory via a read operation on a malfunctioning
    CD-ROM drive. (CVE-2013-2164)

  - The sctp_sf_do_5_2_4_dupcook function in net/sctp/sm_statefuns.c in the SCTP implementation in the Linux
    kernel before 3.8.5 does not properly handle associations during the processing of a duplicate COOKIE ECHO
    chunk, which allows remote attackers to cause a denial of service (NULL pointer dereference and system
    crash) or possibly have unspecified other impact via crafted SCTP traffic. (CVE-2013-2206)

  - A certain Red Hat patch for the Linux kernel 2.6.32 on Red Hat Enterprise Linux (RHEL) 6 allows local
    users to cause a denial of service (invalid free operation and system crash) or possibly gain privileges
    via a sendmsg system call with the IP_RETOPTS option, as demonstrated by hemlock.c. NOTE: this
    vulnerability exists because of an incorrect fix for CVE-2012-3552. (CVE-2013-2224)

  - The ip6_sk_dst_check function in net/ipv6/ip6_output.c in the Linux kernel before 3.10 allows local users
    to cause a denial of service (system crash) by using an AF_INET6 socket for a connection to an IPv4
    interface. (CVE-2013-2232)

  - The (1) key_notify_sa_flush and (2) key_notify_policy_flush functions in net/key/af_key.c in the Linux
    kernel before 3.10 do not initialize certain structure members, which allows local users to obtain
    sensitive information from kernel heap memory by reading a broadcast message from the notify interface of
    an IPSec key_socket. (CVE-2013-2234)

  - The key_notify_policy_flush function in net/key/af_key.c in the Linux kernel before 3.9 does not
    initialize a certain structure member, which allows local users to obtain sensitive information from
    kernel heap memory by reading a broadcast message from the notify_policy interface of an IPSec key_socket.
    (CVE-2013-2237)

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