Package        : vzctl
CVE ID         : not yet available

It was discovered that vzctl, a set of control tools for the OpenVZ
server virtualisation solution, determined the storage layout of
containers based on the presense of an XML file inside the container.
An attacker with local root privileges in a simfs-based container
could gain control over ploop-based containers. Further information on
the prerequites of such an attack can be found at
https://src.openvz.org/projects/OVZL/repos/vzctl/commits/9e98ea630ac0e88b44e3e23c878a5166aeb74e1c

The oldstable distribution (wheezy) is not affected.

For the stable distribution (jessie), this problem has been fixed in
version 4.8-1+deb8u2. During the update existing configurations are

For the unstable distribution (sid), this problem has been fixed in
