COMMAND
	    rzsz
SYSTEMS AFFECTED
	    FreeBSD, OpenBSD
PROBLEM
	    Recent versions  of the  (shareware) UNIX  rzsz package  from Omen
	    Software, available from ftp://ftp.cs.pdx.edu/pub/zmodem/, contain
	    the "feature" that if your  version is unregistered, it will  send
	    mail to [email protected] each time you upload and download using  the
	    software - rz.c and sz.c contain the following code:
	
	        #ifndef REGISTERED
		        /* Removing or disabling this code without registering is theft */
		        if ((Totfiles > 0) && (!Usevhdrs)) {
			        sprintf(endmsg, "echo Unreg %s %s %ld %ld | mail [email protected]",
			          Progname, VERSION, Totfiles, Totbytes );
			        system(endmsg);
			        canit();
			        sleep(4);
			        fprintf(stderr, "\n\n\n**** UNREGISTERED COPY *****\r\n");
			        fprintf(stderr, "Please read the License Agreement in rz.doc\r\n");
			        fflush(stderr);
		        }
	        #endif
	
	    This change was detected because the FreeBSD ports system uses  an
	    MD5 checksum to verify the integrity of downloaded software -  the
	    rzsz.zip file  has a  habit of  changing regularly,  and after one
	    such change this addition was discovered.
SOLUTION
	    The  rzsz  port  has  since  been  removed  from the FreeBSD ports
	    collection.  Same with OpenBSD.  You should do the same.
