    Summary: Updated lxc packages fix security vulnerabilities

    Details: Roman Fiedler discovered a directory traversal flaw in lxc-attach. An attacker with access to an LXC container could exploit this flaw to access files outside of the container (CVE-2016-8649). Jann Horn discovered that LXC incorrectly verified permissions when creating virtual network interfaces. A local attacker could possibly use this issue to create virtual network interfaces in network namespaces that they do not own (CVE-2017-5985). The lxc package has been updated to version 1.0.10 to fix these issues and other bugs.
