    description Roman Fiedler discovered that LXC had a directory traversal flaw when creating lock files. A local attacker could exploit this flaw to create an arbitrary file as the root user. (CVE-2015-1331) Roman Fiedler discovered that LXC incorrectly trusted the container's proc filesystem to set up AppArmor profile changes and SELinux domain transitions. A local attacker could exploit this flaw to run programs inside the container that are not confined by AppArmor or SELinux. (CVE-2015-1334). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
