Unfortunately, it also introduced a regression that prevented the\nCeph network filesystem from being used. This update fixes the problem.\n\nWe apologize for the inconvenience.\n\nOriginal advisory details:\n\n Mohamed Ghannam discovered that a use-after-free vulnerability existed in\n the Netlink subsystem (XFRM) in the Linux kernel. A local attacker could\n use this to cause a denial of service (system crash) or possibly execute\n arbitrary code. (CVE-2017-16939)\n\n It was discovered that the Linux kernel did not properly handle copy-on-\n write of transparent huge pages. A local attacker could use this to cause a\n denial of service (application crashes) or possibly gain administrative\n privileges. (CVE-2017-1000405)\n\n Fan Wu, Haoran Qiu, and Shixiong Zhao discovered that the associative array\n implementation in the Linux kernel sometimes did not properly handle adding\n a new entry. A local attacker could use this to cause a denial of service\n (system crash). (CVE-2017-12193)\n\n Andrey Konovalov discovered an out-of-bounds read in the GTCO digitizer USB\n driver for the Linux kernel. A physically proximate attacker could use this\n to cause a denial of service (system crash) or possibly execute arbitrary\n code.
