       Debian Security Advisory                             security@debian.org

       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.

       Debian GNU/Linux 2.1 alias slink
       - --------------------------------

         This version of Debian was released only for Intel, the Motorola
         680x0, the alpha and the Sun sparc architecture.
