Yderligere oplysninger:

Rudolf Polzer har opdaget en sårbarhed i a2ps, et konverterings- og forskønnelsesprogram for mange formater til PostScript. Programmet indkapslede ikke shell-metategn korrekt, hvilket kunne gøre det muligt at udføre vilkårlige kommandoer som en priviligeret bruger, hvis a2ps var installeret som et printer-filter.

I den stabile distribution (woody) er dette problem rettet i version 4.13b-16woody1.

I den ustabile distribution (sid) er dette problem rettet i version 1:4.13b-4.2.

Vi anbefaler at du opgraderer din a2ps-pakke.

Rettet i:

Debian GNU/Linux 3.0 (woody)
