FreeBSD : rssh -- file name disclosure bug (a4815970-c5cc-11d8-8898-000d6111a684)

This script is Copyright (C) 2009-2015 Tenable Network Security, Inc.


Synopsis :

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

Description :

rssh expands command line parameters before invoking chroot. This could
result in the disclosure to the client of file names outside of the
chroot directory. A posting by the rssh author explains :

The cause of the problem identified by Mr. McCaw is that rssh expanded
command-line arguments prior to entering the chroot jail. This bug
DOES NOT allow a user to access any of the files outside the jail, but
can allow them to discover what files are in a directory which is
outside the jail, if their credentials on the server would normally
allow them read/execute access in the specified directory.
