Yderligere oplysninger:

Steve Kemp har opdaget et bufferoverløb i xpcd-svga, der kan udløses med en lang HOME-miljøvariabel. Denne sårbarhed kunne udnyttes af en lokal angriber til at opnå root-rettigheder.

I den stabile distribution (woody) er dette problem rettet i version 2.08-8woody1.

I den ustabile distribution (sid) vil dette problem snart blive rettet.

Vi anbefaler at du opdaterer din xpcd-pakke.
