    It was discovered that twiki, a web based collaboration platform, didn't properly sanitize the image parameter in its configuration script. This could allow remote users to execute arbitrary commands upon the system, or read any files which were readable by the webserver user.

    It was discovered that twiki, a web based collaboration platform,
    didn't properly sanitize the image parameter in its configuration script.
    This could allow remote users to execute arbitrary commands upon the 
    system, or read any files which were readable by the webserver user.
    
    For the stable distribution (etch), this problem has been fixed in version
    1:4.0.5-9.1etch1.
    
    For the unstable distribution (sid), this problem will be fixed soon.
    
    We recommend that you upgrade your twiki package.
    
    
    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.
