The LXC driver (lxc/lxc_driver.c) in libvirt 1.0.1 through 1.2.1 allows local users to (1) delete arbitrary host devices via the virDomainDeviceDettach API and a symlink attack on /dev in the container; (2) create arbitrary nodes (mknod) via the virDomainDeviceAttach API and a symlink attack on /dev in the container; and cause a denial of service (shutdown or reboot host OS) via the (3) virDomainShutdown or (4) virDomainReboot API and a symlink attack on /dev/initctl in the container, related to "paths under /proc/$PID/root" and the virInitctlSetRunLevel function.

Security readout for executives and security teams

CVE-2013-6456 affects libvirt’s LXC driver. A local user with the right container/API access could abuse symlinks inside an LXC container to affect the host, including deleting or creating device nodes or triggering host shutdown/reboot behavior. Exposure is most likely on older systems running libvirt 1.0.1-1.2.1 with the LXC driver enabled, especially where local users or container operators can invoke libvirt domain device or lifecycle APIs. Prioritize remediation for any remaining legacy libvirt LXC hosts. The issue requires local/container-level access, but the potential blast radius includes host availability and device integrity. Mitigation focus: Upgrade libvirt using the relevant vendor-supported fixed package or later release.; Restrict libvirt API access to trusted administrative users only.; Avoid untrusted multi-tenant LXC workloads on affected libvirt versions..
