A local attacker could use this to bypass access controls on resources outside the namespace. (CVE-2018-18955)</p> <p>Philipp Wendler discovered that the overlayfs implementation in the Linux kernel did not properly verify the directory contents permissions from within a unprivileged user namespace. A local attacker could use this to expose sensitive information (protected file names).
