	The ndcfg command raises its privileges with the security

	malicious user to run code of their choice with raised
	privileges.


2. Vulnerable Supported Versions

	System				Binaries
	----------------------------------------------------------------------
	UnixWare 7.1.1			/usr/lib/netcfg/bin/ndcfg
