    Package        : kernel-patch-vserver
    Vulnerability  : programming error
    Problem-Type   : local
    Debian-specific: no
    CVE ID         : CVE-2006-2110
    
    Jan Rekorajski discovered that the kernel patch for virtual private servers
    does not limit context capabilities to the root user within the virtual
    server, which might lead to privilege escalation for some virtual server
    specific operations.
    
    The old stable distribution (woody) does not contain kernel-patch-vserver
    packages.
    
    For the stable distribution (sarge) this problem has been fixed in
    version 1.9.5.6.
    
    For the unstable distribution (sid) this problem has been fixed in
    version 2:2.0.1-4.
    
    We recommend that you upgrade your kernel-patch-vserver package and
    rebuild your kernel immediately.
    
    
    Upgrade Instructions
    - --------------------
    
    wget url
            will fetch the file for you
    dpkg -i file.deb
            will install the referenced file.
    
    If you are using the apt-get package manager, use the line for
    sources.list as given below:
    
    apt-get update
            will update the internal database
    apt-get upgrade
            will install corrected packages
    
    You may use an automated update by adding the resources from the
    footer to the proper configuration.

      its next update.
