    Package        : kernel-patch-vserver, util-vserver
    Vulnerability  : missing attribute support
    Problem type   : local (remote)
    Debian-specific: yes
    CVE IDs        : CVE-2005-4347 CVE-2005-4418
    Debian Bugs    : 329087 329090
    Several vulnerabilities have been discovered in the Debian vserver
    support for Linux.  The Common Vulnerabilities and Exposures project
    identifies the following problems:
        Bj�rn 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.
        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.
    For the stable distribution (sarge) this problem has been fixed in
    version of kernel-patch-vserver and in version
    0.30.204-5sarge3 of util-vserver.
    For the unstable distribution (sid) this problem has been fixed in
    version 2.3 of kernel-patch-vserver and in version 0.30.208-1 of
    We recommend that you upgrade your util-vserver and
    kernel-patch-vserver packages and build a new kernel immediately.
