Debian DSA-091-1 : ssh - influencing login

high Nessus Plugin ID 14928

Synopsis

The remote Debian host is missing a security-related update.

Description

If the UseLogin feature is enabled in 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 if UseLogin is enabled.

Please note that the default configuration for Debian does not have UseLogin enabled.

Solution

This has been fixed in version 1:1.2.3-9.4.
