Ytterligare information:

Johnny Mast upptäckte ett buffertspill i libast, biblioteket för blandade skojiga saker, vilket kunde leda till exekvering av godtycklig kod. Biblioteket används av eterm, vilket installeras setgid uid, vilket leder till en sårbarhet där utmp-filen kunde ändras.

För den gamla stabila utgåvan (Woody) har detta problem rättats i version 0.4-3woody2.

För den stabila utgåvan (Sarge) har detta problem rättats i version 0.6-0pre2003010606sarge1.
