Yderligere oplysninger:

"infamous41md" og Chris Evans har fundet flere heap-baserede bufferoverløb i xpdf, Portable Document Format (PDF)-programsamlingen, som også findes i libextractor, et bibliotek til udtræk af vilkårlige metadata fra filer, hvilket kunne medføre et lammelsesangreb (denial of service) ved at få programmet til at gå ned eller muligvis udføre vilkårlig kode.

Den gamle stabile distribution (woody) indeholder ikke libextractor-pakker.

I den stabile distribution (sarge) er disse problemer rettet i version 0.4.2-2sarge2.

I den ustabile distribution (sid) vil disse problemer snart blive rettet.

Vi anbefaler at du opgraderer dine libextractor-pakker.

Rettet i:

Debian GNU/Linux 3.1 (sarge)
