The behavior didn't follow what was documented in the lxc-user-nic(1) man page: It ensures that the calling user is privileged over the network namespace to which the interface will be attached. This issue is CVE-2017-5985. https://lists.linuxcontainers.org/pipermail/lxc-users/2017-March/012925.html https://launchpad.net/bugs/1654676 https://github.com/lxc/lxc/commit/16af238036a5464ae8f2420ed3af214f0de875f9 Tyler Download attachment "signature.asc" of type "application/pgp-signature" (802 bytes)
