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.
