can be used to create files in group sys writeable directories.
SCOs sadc runs euid root, and therefore can be used to create
files anywhere on the filesystem.

other vulnerable systems, users may have improved chances of
gaining root access.
REPEAT BY:
Exploit details will not be made available, until patches have
been provided.
FIX:

WORKAROUND:
In the meantime, limit access to sadc by changing mode on
/usr/lib/sa.
