A local attacker\ncould use this to bypass access controls on resources outside the\nnamespace. (CVE-2018-18955)\n\nPhilipp Wendler discovered that the overlayfs implementation in the Linux\nkernel did not properly verify the directory contents permissions from\nwithin a unprivileged user namespace. A local attacker could use this to\nexpose sensitive information (protected file names). (CVE-2018-6559)\n",
