CVE-2015-1331 
Roman Fiedler discovered a directory traversal flaw in LXC when
creating lock files. A local attacker could exploit this flaw to
create an arbitrary file as the root user.

CVE-2015-1334 
Roman Fiedler discovered that LXC incorrectly trusted the
container's proc filesystem to set up AppArmor profile changes and
SELinux domain transitions. A malicious container could create a
fake proc filesystem and use this flaw to run programs inside the
container that are not confined by AppArmor or SELinux.");
