This update provides the corresponding updates for the Linux\nHardware Enablement (HWE) kernel from Ubuntu 18.04 LTS for Ubuntu\n16.04 LTS.\n\nIt was discovered that memory present in the L1 data cache of an Intel CPU\ncore may be exposed to a malicious process that is executing on the CPU\ncore. This vulnerability is also known as L1 Terminal Fault (L1TF). A local\nattacker in a guest virtual machine could use this to expose sensitive\ninformation (memory from other guests or the host OS). (CVE-2018-3646)\n\nIt was discovered that memory present in the L1 data cache of an Intel CPU\ncore may be exposed to a malicious process that is executing on the CPU\ncore. This vulnerability is also known as L1 Terminal Fault (L1TF). A local\nattacker could use this to expose sensitive information (memory from the\nkernel or other processes). (CVE-2018-3620)\n\nJuha-Matti Tilli discovered that the IP implementation in the Linux kernel\nperformed algorithmically expensive operations in some situations when\nhandling incoming packet fragments. A remote attacker could use this to\ncause a denial of service. (CVE-2018-5391)\n",
