This update provides the corresponding updates for the Linux\nHardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu\n14.04 LTS.\n\nIt was discovered that a buffer overflow existed in the Bluetooth stack of\nthe Linux kernel when handling L2CAP configuration responses. A physically\nproximate attacker could use this to cause a denial of service (system\ncrash). (CVE-2017-1000251)\n\nIt was discovered that the Flash-Friendly File System (f2fs) implementation\nin the Linux kernel did not properly validate superblock metadata. A local\nattacker could use this to cause a denial of service (system crash) or\npossibly execute arbitrary code. (CVE-2017-10663)\n\nIt was discovered that a buffer overflow existed in the ioctl handling code\nin the ISDN subsystem of the Linux kernel.
