    Package        : wget
    Vulnerability  : missing input sanitization
    Problem type   : local (remote)
    Debian-specific: no
    CVE Id(s)      : CVE-2010-2252
    Debian Bug     : 590296
    
    It was discovered that wget, a command line tool for downloading files
    from the WWW, uses server-provided file names when creating local
    files.  This may lead to code execution in some scenarios.
    
    After this update, wget will ignore server-provided file names.  You
    can restore the old behavior in cases where it is not desirable by
    invoking wget with the new --use-server-file-name option.
    
    For the stable distribution (lenny), this problem has been fixed in
    version 1.11.4-2+lenny2.
    
    For the unstable distribution (sid), this problem will be fixed soon.
    
    We recommend that you upgrade your wget 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.
