OpenServer 5.0.7, OpenServer 5.0.6, and OpenServer 5.0.5 are vulnerable
to two (2) distinct exploits.  Namely,

1) Xsco can be locally exploited by any valid user in order to escalate
their privileges to 'root'.  The bug is due to improper input handling
when running the command line switch '-co'.

2) There is a vulnerability in the MIT-SHM extension within
all X servers that are running as root.  Any user with local X access 
can exploit the MIT-SHM extension and gain read/write access to any 
shared memory segment on the system.

*** This plugin relied on the banner of the remote system
*** to determine that it is a SCO Unix server, so this alert
*** might be a false positive
