This update provides the corresponding updates for the Linux\nHardware Enablement (HWE) kernel from Ubuntu 18.04 LTS for Ubuntu\n16.04 LTS.\n\nFelix Wilhelm discovered that the Xen netback driver in the Linux kernel\ndid not properly perform input validation in some situations. An attacker\ncould use this to cause a denial of service (system crash) or possibly\nexecute arbitrary code. (CVE-2018-15471)\n\nIt was discovered that the generic SCSI driver in the Linux kernel did not\nproperly enforce permissions on kernel memory access. A local attacker\ncould use this to expose sensitive information or possibly elevate\nprivileges. (CVE-2017-13168)\n\nIt was discovered that an integer overflow existed in the CD-ROM driver of\nthe Linux kernel. A local attacker could use this to expose sensitive\ninformation (kernel memory). (CVE-2018-16658)\n\nIt was discovered that an integer overflow existed in the HID Bluetooth\nimplementation in the Linux kernel that could lead to a buffer overwrite.\nAn attacker could use this to cause a denial of service (system crash) or\npossibly execute arbitrary code.
