    Package        : unzip
    Vulnerability  : race condition
    Problem type   : local
    Debian-specific: no
    CVE ID         : CAN-2005-2475
    BugTraq ID     : 14450
    Debian Bug     : 321927
    
    Imran Ghory discovered a race condition in the permissions setting
    code in unzip.  When decompressing a file in a directory an attacker
    has access to, unzip could be tricked to set the file permissions to a
    different file the user has permissions to.
    
    For the old stable distribution (woody) this problem has been fixed in
    version 5.50-1woody4.
    
    For the stable distribution (sarge) this problem has been fixed in
    version 5.52-1sarge2.
    
    For the unstable distribution (sid) this problem has been fixed in
    version 5.52-4.
    
    We recommend that you upgrade your unzip 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.

      These files will probably be moved into the stable distribution on
      its next update.
