Plus de précisions :

« infamous41md » et Chris Evans ont découvert plusieurs dépassements de pile dans xpdf, un visualisateur de fichiers PDF, qui étaient aussi présents dans libextractor, une bibliothèque d'extraction de métadonnées des fichiers. Ces dépassements pouvaient mener à un déni de service en plantant l'application ou éventuellement à l'exécution de code arbitraire.

L'ancienne distribution stable (Woody) ne contient pas libextractor.

Pour l'actuelle distribution stable (Sarge), ces problèmes ont été corrigés dans la version 0.4.2-2sarge2.

Pour la distribution instable (Sid), ces problèmes seront bientôt corrigés.

Nous vous recommandons de mettre à jour vos paquets libextractor.

Corrigé dans :

Debian GNU/Linux 3.1 (sarge)
