    CVE-2019-5736

    Summary: Updated lxc packages fix security vulnerability

    Details: LXC allows attackers to overwrite the host LXC binary (and consequently obtain host root access) by leveraging the ability to execute a command as root within one of these types of containers: a new container with an attacker-controlled image, or an existing container, to which the attacker previously had write access. This occurs because of file-descriptor mishandling, related to /proc/self/exe. This attack is only possible with privileged containers since it requires root privilege on the host to overwrite the binary.
