CONECTIVA LINUX SECURITY ANNOUNCEMENT
PACKAGE   : openssh
SUMMARY   : X11 and ssh-agent forwarding problems
DATE      : 2000-12-06 15:19:00
ID        : CLA-2000:351
RELEVANT
RELEASES  : 6.0

DESCRIPTION
(This is a specific update for Conectiva Linux 6.0 which has already been applied to previous versions.) In versions prior to 2.3.0, if the openssh client receives a request for ssh-agent or X11 forwarding, it does not check if this feature has been negotiated during session setup and grants access. This could allow remote access to the client's display and ssh-agent service.

SOLUTION
All openssh users should upgrade immediately.
