DESCRIPTION:
Pasquale Minervini has reported a vulnerability in SCO OpenServer,
which can be exploited by malicious, local users to gain escalated
privileges.

The vulnerability is caused due to a boundary error in the nwclient
utility when processing command line arguments. This can be exploited
to cause a buffer overflow by passing an overly long argument.
