vzctl is a set of control tools for the OpenVZ server virtualization + solution. +

+
+ +

It was discovered that vzctl determined the virtual environment (VE) + layout based on the presence of root.hdd/DiskDescriptor.xml in the VE + private directory. This allows local simfs container (CT) root users to + change the root password for arbitrary ploop containers. This is + demonstrated by a symlink attack on the ploop container root.hdd file + which can then be used to access a control panel. +

+
+ +

An attacker with root privileges, in a simfs-based container, could gain + control over ploop-based containers. +

+
+ +

There is no known workaround at this time.

+
+ +

All vzctl users should upgrade to the latest version:

+ + + # emerge --sync + # emerge --ask --oneshot --verbose ">=sys-cluster/vzctl-4.9.4" + +
