"Several vulnerabilities have been discovered in the Debian vserver
support for Linux. The Common Vulnerabilities and Exposures project
identifies the following problems :

  - CVE-2005-4347
    Bjorn Steinbrink discovered that the chroot barrier is
    not set correctly with util-vserver which may result in
    unauthorised escapes from a vserver to the host system.

  This vulnerability is limited to the 2.4 kernel patch included in
  kernel-patch-vserver. The correction to this problem requires
  updating the util-vserver package as well and installing a new
  kernel built from the updated kernel-patch-vserver package.

  - CVE-2005-4418
    The default policy of util-vserver is set to trust all
    unknown capabilities instead of considering them as
    insecure."
