Yderligere oplysninger:

Christophe Bailleux rapporterede på bugtraq at Xvt er sårbar overfor et bufferoverløb i dets håndtering af parametre. Da Xvt installeres som "setuid root", var det muligt for en almindelig bruger at starte Xvt med nøje fremstillede parametre, således at Xvt kørte en root-shell.

Vedligeholderen har rettet problemet i version 2.1-13 aff Xvt i Debian-unstable og 2.1-13.0potato.1 den stabile Debian GNU/Linux 2.2.

Vi anbefaler at du omgående opgraderer din xvt-pakke.

Rettet i:

Debian GNU/Linux 2.2 (potato)
