    Package        : userv
    Problem type   : local exploit
    Debian-specific: no
    
    The version of userv that was distributed with Debian GNU/Linux 2.1 / slink
    had a problem in the fd swapping algorithm: it could sometimes make an
    out-of-bounds array reference. It might be possible for local users
    to abuse this to carry out unauthorised actions or be able to take
    control for service user accounts.
    
    This has been fixed in version 1.0.1.0slink for Debian 2.1, and
    version 1.0.1.1potato for Debian 2.2 .
    
    We recommend you upgrade your uesrv package immediately.
    
    wget url
            will fetch the file for you
    dpkg -i file.deb
            will install the referenced file.
