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 automatically updated. For the testing distribution (stretch), this problem has been fixed in version 4.9.4-2. For the unstable distribution (sid), this problem has been fixed in version 4.9.4-2. We recommend that you upgrade your vzctl packages.
