    Trustix developers discovered insecure temporary file creation in
    supplemental scripts in the gzip package which may allow local users
    to overwrite files via a symlink attack.
    
    For the stable distribution (woody) these problems have been fixed in
    version 1.3.2-3woody3.
    
    The unstable distribution (sid) is not affected by these problems.
    
    We recommend that you upgrade your gzip 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.
