  virtual machines. This update fixes the problem.

  We apologize for the inconvenience.

  Original advisory details:

  halfdog discovered that OverlayFS, when mounting on top of a FUSE mount,
  incorrectly propagated file attributes, including setuid. A local
  unprivileged attacker could use this to gain privileges. (CVE-2016-1576)

  halfdog discovered that OverlayFS in the Linux kernel incorrectly
  propagated security sensitive extended attributes, such as POSIX ACLs. A
  local unprivileged attacker could use this to gain privileges.
  (CVE-2016-1575)

  It was discovered that the Linux kernel did not properly enforce rlimits
  for file descriptors sent over UNIX domain sockets. A local attacker could
  use this to cause a denial of service. (CVE-2013-4312)

  It was discovered that the Linux kernel's Filesystem in Userspace (FUSE)
  implementation did not handle initial zero length segments properly. A
  local attacker could use this to cause a denial of service (unkillable
  task). (CVE-2015-8785)

  Andy Lutomirski discovered a race condition in the Linux kernel's
  translation lookaside buffer (TLB) handling of flush events. A local
  attacker could use this to cause a denial of service or possibly leak
  sensitive information. (CVE-2016-2069)");
