Description
-----------
We have received a report from SGI that a vulnerability has been
discovered in the seyon program. This can lead to a root
compromise. Any user who can execute the seyon program can
exploit this vulnerability.
Since SGI does not provide exploit information, we are unable to
fix the problem. SGI provided such information only to recognized
security response/incident/coordination organizations and bugtraq
doesn't seem to be accepted. SGI doesn't develop patches to third
party products, thus there is no chance for a quick fix.
Vulnerability
-------------
Since a root compromise needs an executable that runs as root we
tend to belive that this needs a setuid seyon. The Seyon package
as provided with Debian GNU/Linux does *not* run setuid root.
Thus we doubt that the seyon package as provided with Debian
GNU/Linux can be used to exploit root if you don't change the
default behaviour.
