 +**lxc-2.0.9_d3a03247**: ​ Upgraded.
 +This update fixes a security issue where a malicious privileged container
 +could overwrite the host binary and thus gain root-level code execution on
 +the host. As the LXC project considers privileged containers to be unsafe
 +no CVE has been assigned for this issue for LXC. To prevent this attack,
 +LXC has been patched to create a temporary copy of the calling binary
 +itself when it starts or attaches to containers. To do this LXC creates an
 +anonymous, in-memory file using the memfd_create() system call and copies
 +itself into the temporary in-memory file, which is then sealed to prevent
 +further modifications. LXC then executes this sealed, in-memory file
 +instead of the original on-disk binary.
 +For more information,​ see:
