    Vulnerability  : missing input sanitization
    Problem type   : local

    Debian Bug     : 585394
    
    
    Anders Kaseorg and Evan Broder discovered a vulnerability in sudo, a
    program designed to allow a sysadmin to give limited root privileges to
    users, that allows a user with sudo permissions on certain programs to
    use those programs with an untrusted value of PATH.
    This could possibly lead to certain intended restrictions being bypassed,
    such as the secure_path setting.
    
    
    For the stable distribution (lenny), this problem has been fixed in
    version 1.6.9p17-3
    
    For the unstable distribution (sid), this problem has been fixed in
    version 1.7.2p7-1, and will migrate to the testing distribution (squeeze)
    shortly.
    
    
    We recommend that you upgrade your sudo 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.
