announced via advisory DSA 1011-1.

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

Bjørn 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.

The old stable distribution (woody) does not contain a
kernel-patch-vserver package.";
