    linux vulnerabilities
    A security issue affects these releases of Ubuntu and its derivatives:
    - Ubuntu 12.04 LTS
    Several security issues were fixed in the kernel.
    Software Description:
    - linux: Linux kernel
    Kangjie Lu discovered an information leak in the Reliable Datagram Sockets
    (RDS) implementation in the Linux kernel. A local attacker could use this
    to obtain potentially sensitive information from kernel memory.
    Yue Cao et al discovered a flaw in the TCP implementation's handling of
    challenge acks in the Linux kernel. A remote attacker could use this to
    cause a denial of service (reset connection) or inject content into an TCP
    stream. (CVE-2016-5696)
    It was discovered that a heap based buffer overflow existed in the USB HID
    driver in the Linux kernel. A local attacker could use this cause a denial
    of service (system crash) or possibly execute arbitrary code.
    Update instructions:
    The problem can be corrected by updating your system to the following
    package versions:
    Ubuntu 12.04 LTS:
      linux-image-3.2.0-109-generic   3.2.0-109.150
      linux-image-3.2.0-109-generic-pae  3.2.0-109.150
      linux-image-3.2.0-109-highbank  3.2.0-109.150
      linux-image-3.2.0-109-omap      3.2.0-109.150
      linux-image-3.2.0-109-powerpc-smp  3.2.0-109.150
      linux-image-3.2.0-109-powerpc64-smp  3.2.0-109.150
      linux-image-3.2.0-109-virtual   3.2.0-109.150
    After a standard system update you need to reboot your computer to make
    all the necessary changes.
    ATTENTION: Due to an unavoidable ABI change the kernel updates have
    been given a new version number, which requires you to recompile and
    reinstall all third party kernel modules you might have installed.
    Unless you manually uninstalled the standard kernel metapackages
    (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
    linux-powerpc), a standard system upgrade will automatically perform
    this as well.
      CVE-2016-5244, CVE-2016-5696, CVE-2016-5829
