    Debian-specific: no
    CVE Ids        : CVE-1999-1332, CAN-2003-0367
    
    Paul Szabo discovered that znew, a script included in the gzip
    package, creates its temporary files without taking precautions to
    avoid a symlink attack (CAN-2003-0367).
    
    The gzexe script has a similar vulnerability which was patched in an
    earlier release but inadvertently reverted.
    
    For the stable distribution (woody) both problems have been fixed in
    version 1.3.2-3woody1.
    
    For the old stable distribution (potato) CAN-2003-0367 has been fixed
    in version 1.2.4-33.2.  This version is not vulnerable to
    CVE-1999-1332 due to an earlier patch.
    
    For the unstable distribution (sid) this problem will be fixed soon.
    
    We recommend that you update 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.
