Or remove/don't install dmedia_eoe.sw.synth.  Though it's included on
standard install of IRIX on newly purchased SGI's, it isn't one of the
packages installed when building a new OS from the 6.5.x CDROMs.

Better yet, follow Security Focus and SGI security lists at the URLs
below.  Both Security Focus and SGI have had a security advisory on
the midikeys vulnerability out since May 1999.  Both advisories
suggested the above fix.

Said another way, there was nothing new about the irix-soundplayer.sh
script -- it exploited a fairly old, widely known vulnerability that
should be fixed on any properly maintained IRIX box.  If your machine
still had that hole open, it's likely got several other problems
waiting for the script kiddies to exploit.

The first step in securing any system is realizing the the vendor
didn't do it for you....
