    Package        : ssh
    Problem type   : influencing login
    Debian-specific: no
    If the UseLogin feature is enabled in for ssh local users could
    pass environment variables (including variables like LD_PRELOAD)
    to the login process. This has been fixed by not copying the
    environment of UseLogin is enabled.
    Please note that the default configuration for Debian does not
    have the UseLogin enabled.
    This has been fixed in version 1:1.2.3-9.4.
