There seems to be a vulnerbility in dg/ux (tested in 5.4r3.10) - it
includes ospf_monitor (from the gated package). Unfortunately, it is a
older version and has a security hole.

It is a suid program, and has a command to write to a file, so something
like this:

umask 0
F /tmp/foo

This should create a 0 byte world writable file called /tmp/foo, assuming
/tmp/foo does not exist. If it exists, it will be truncated, permissions
obviously will not be modified.
