"The remote Oracle Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the
ELSA-2014-07401 advisory.

  - The rds_ib_laddr_check function in net/rds/ib.c in the Linux kernel before 3.12.8 allows local users to
    cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other
    impact via a bind system call for an RDS socket on a system that lacks RDS transports. (CVE-2013-7339)

  - The raw_cmd_copyin function in drivers/block/floppy.c in the Linux kernel through 3.14.3 does not properly
    handle error conditions during processing of an FDRAWCMD ioctl call, which allows local users to trigger
    kfree operations and gain privileges by leveraging write access to a /dev/fd device. (CVE-2014-1737)

  - The raw_cmd_copyout function in drivers/block/floppy.c in the Linux kernel through 3.14.3 does not
    properly restrict access to certain pointers during processing of an FDRAWCMD ioctl call, which allows
    local users to obtain sensitive information from kernel heap memory by leveraging write access to a
    /dev/fd device. (CVE-2014-1738)

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