"The remote Oracle Linux 5 / 6 host has packages installed that are affected by multiple vulnerabilities as referenced in
the ELSA-2014-3086 advisory.

  - include/linux/netdevice.h in the Linux kernel before 2.6.36 incorrectly uses macros for netdev_printk and
    its related logging implementation, which allows remote attackers to cause a denial of service (NULL
    pointer dereference and system crash) by sending invalid packets to a VxLAN interface. (CVE-2014-3535)

  - Race condition in the __kvm_migrate_pit_timer function in arch/x86/kvm/i8254.c in the KVM subsystem in the
    Linux kernel through 3.17.2 allows guest OS users to cause a denial of service (host OS crash) by
    leveraging incorrect PIT emulation. (CVE-2014-3611)

  - Multiple buffer overflows in the command_port_read_callback function in drivers/usb/serial/whiteheat.c in
    the Whiteheat USB Serial Driver in the Linux kernel before 3.16.2 allow physically proximate attackers to
    execute arbitrary code or cause a denial of service (memory corruption and system crash) via a crafted
    device that provides a large amount of (1) EHCI or (2) XHCI data associated with a bulk response.
    (CVE-2014-3185)

  - Multiple stack-based buffer overflows in the magicmouse_raw_event function in drivers/hid/hid-magicmouse.c
    in the Magic Mouse HID driver in the Linux kernel through 3.16.3 allow physically proximate attackers to
    cause a denial of service (system crash) or possibly execute arbitrary code via a crafted device that
    provides a large amount of (1) EHCI or (2) XHCI data associated with an event. (CVE-2014-3181)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
