Ytterligare information:

Versionen av textskärmbiblioteket ncurses som medföljde Debian GNU/Linux 2.2 är sårbart för flera buffertspill i tolkningen av terminfodatabasfilerna. Detta problem upptäcktes av Jouko Pynnönen <jouko@solutions.fi>. Problemen kan endast utnyttjas i "setuid"-flaggade binärer länkade mot ncurses, och som använder just dessa funktioner, bland andra xmcd-versioner före 2.5pl1-7.1.

Problemet har rättats i ncurses 5.0-6.0potato1 för Debian GNU/Linux 2.2, och i ncurses 5.0-8 för Debian unstable.
